CT neck and larynx area may be required if there is a suspicion of chronic or tumor disease of this anatomical zone. This diagnostic method will give exhaustive information on the health of the initial respiratory departments and a number of other systems.

Under CT, the laryngess means a radiographic method for assessing the morphological changes that occur in the specified area of \u200b\u200bthe body. The method is based on the X-ray properties penetrate through soft fabrics, Load in dense structures and allow them to visualize them on medical pictures. Glowing computed tomography - the most accurate tool method Diagnostics, giving an idea of \u200b\u200babsolutely any types of pathologies:

• Dystrophic
• Inflammatory
• Degenerative
• Tumor
• Destructive

Tomograph during the procedure makes many layers with a slice size from 1 mm to 0.5 cm depending on the type of machine. Snapshots of the CT will be presented in the form of a three-dimensional picture, besides, the scan is carried out in several projections. This approach makes tomography data very accurate, and even the slightest changes in the fabric state will be almost impossible. Even more detailed information gives MSCT larynx, where the number of cuts is more significant.

CT larynx when conducting will show not only the top airways. The observation zone of tomography falls:

• Thyroid
• Parathyroid gland
• Regional lymphatic nodes
• Blood vessels
• Upper diver of esophageal

Contrast gain with CT and diagnosis of larynx cancer

Huge importance is playing in the diagnosis of cancer diseases. The usual CT, no doubt, is very accurate, but for non-invasive differentiation of oncological tumors and benign neoplasms can be recommended by CT with contrast. The procedure will help identify:

1. Primary tumor processes at any stage, including - in the larynx, voice bundles, parachitoid, thyroid gland, lymph nodes.
2. Secondary (metastatic) cancer from other bodies, including remote.
3. Benign tumors - adenoma, papillomas, cysts, polyps and their other types.
4. Tumors subject to malignization or already reborn into cancer.
5. The degree of growth of cancer tumor, stage and presence / lack of metastases.

CT throat and larynx with contrast will help evaluate the effectiveness of the operation or radiation therapy, Chemotherapy for the treatment of cancer pathologies. The clarity of the snapshots increases due to the introduction of a contrast agent - more often they are the preparations of iodine or some metals (lanthanides). The drug has properties to accumulate in patients with tissues, as a result, in the pictures they will be painted in a specific color. The tool is introduced to the patient in Vienna before the examination, after which the CT is performed in the usual and special modes. Where there is a large influx of blood (malignant tumors), CT will show all the information necessary for the diagnosis.

Other indications for the study of throat and larynx

CT Larry is a safe diagnostic procedure that implies the use of minimal radial load. X-ray radiation here is highly different from the usual radiography in its intensity and the direction of the beam. No residual lesion - radiation, ionization - is not observed, so the technique can be used to diagnose any sharp and chronic pathologies Anatomical zone.

• Traumatic damage to the throat, larynx, neck
• Changes in lymph nodes
• Any neoplasms
• Goiter and other thyroid pathologies
• Congenital abnormalities of the structure and structure of organs
• Non-thorn bodies in the area of \u200b\u200bthe larynx, neck
• Pathologies of the upper spine
• Inflammatory throat diseases, larynx
• Diseases of the esophagus
• OUR SURVIVE, OUCENCY OF SOME TIBES

1. Sore throat.
2. Lump in the throat.
3. Difficulty breathing and swallowing.
4. Suffocation.
5. Highland swelling.

How is the diagnosis of CT method

Special preparation when performing CT is not required without contrast. You should come to the designated time, having with you the previous results of the survey or the data of other instrumental techniques. If the use of a contrast agent is planned, it is not necessary to eat 4-6 hours before the examination to avoid pathological reactions by the gastrointestinal tract (they sometimes happen, especially from patients exposed to them).

The study should remove all metal decorations, accessories, remove the phone, all removable medical devices. Diagnosis is carried out in the lying position. The person is placed on the table (couch), which is then rushing under tomograph arc. It is impossible to move at the time of CT. The device, more precisely, its nozzle, begins to move smoothly around the head, making a series of pictures.

The procedure takes about 10-15 minutes. If the study involves the use of contrast, preparation, the introduction of the drug and the CT itself can take 30-40 minutes.

The price of CT Neck, throat, larynx will be 3000-7000 rubles, depending on the status of the clinic, such as the number of contrast agent. The survey in the framework of the MSCT may cost about 5,000 rubles.

This method of diagnosis during pregnancy on any period is strictly contraindicated, since it implies the use of X-ray radiation, albeit in small doses. CT may cause malformations of the fetus, therefore, it is excluded (an alternative can be an MRI anatomical zone). It is also contraindicated to perform CT with a contrast in certain diseases of the kidneys and heart, with allergies to a contrast agent.

Relative contraindications in which the procedure is made only in acute necessity, such:

1. Age up to 16 years.
2. Diseases of the thyroid gland, accompanied by hyperproduction of hormones.
3. Lactation.
4. Hypercines.
5. Strong pain syndrome.
6. Mental disorders.

• Lymphadenit
• Lymphoma
• Diffuse Goob.
• Paragyperosis
• Nodal goiter
• Hyperplasia of the thyroid gland
• Adenoma, cysts of the thyroid, parachitoid glands
• Stenosis and thrombosis of vessels
• Aneurysm
• Cancer Gortani.
• Chronic Larygit
• "Singing nodules"
• Polyposis Larch
• Osteochondrosis of the cervical department
• Heavy stages of angina
• Abscess throat, larynx
• Liquid accumulations and cysts
• Flegmon Shea
• Diverticulus Glows
• Esophageal carcinoma
• Paralysis of Glow
• Stenosis of Gortani.
• False and true croup

CT Large region helps to identify even undiagnosed in the recent past of the disease, rare tumors, which will contribute to the early appointment of therapy or timely operation.

CT Large - non-invasive procedure aimed at obtaining three-dimensional images of the top of the respiratory throat for which you can diagnose different kinds pathologies. Severe two main types of computer diagnostics:

• step-by-step - used if the insertion of a contrast agent is required;
• spiral (single and multi-section) - characterized by less radial load.

Snapshot details are caused by three main factors: immobility of the patient, the use of contrast agent and technical characteristics tomograph.

The most detailed to consider the plot of the respiratory system allow high-policted closed devices, while the low-profile (mostly open type) have less power and are not suitable for identifying tumors in the initial stages.

What does it show?

The study on a computed tomograph helps in the diagnosis of many types of diseases and pathological conditions, including:

• anomalous changes in tissues and bones after infections;
• stenosis, thrombosis and paralysis muscles;
• mechanical damage to the trachea and larynx;
• tracheomalation;
• neoplasms of various localization, degree of development and size, as well as metastases during cancer;
• hyperplasia;
• increased regional lymphatic bonds;
• causes of violation of voice function (swelling, cysts, etc.).

Together with the study of the larynx, CT trachea and bronchi are often prescribed, for example, to test the reasons for the deterioration of the respiratory tract.

If there are suspicions of the large-scale distribution of the disease, then conduct a survey of the entire pharynx.

Indications and contraindications

From key readings To assign this type of diagnostics, it is worth noting:

• the probability of abscess and phlegmon;
• upcoming surgical intervention;
• oncological diseases;
• the presence of seals on mucous membranes;
• the resulting injuries of the neck and throat;
• problems with breathing and / or swallowing;
• vascular pathologies;
• inflammatory processes in chronic and sharp stages.

It is not allowed to hold CT larynx to pregnant women and children under fourteen years old, patients with epilepsy and hyperkinosis, patients in severe condition (connected to IVL, etc.) and people with patients with kidneys and thyroid gland, if a procedure is planned with amplification.

How many last time?

If screening does not imply amplification, then its duration does not exceed 5-10 minutes. After intravenous administration iodine-containing substance to the patient has to be held inside the apparatus about twenty minutes, and in the most fixed state.

How to get a direction for diagnostics?

Doctors of different specializations are engaged in issuing areas for research: pulmonology, oncology, etc. You can make an appointment to the doctor private clinic Or get an appointment on the CT in the usual clinic, but in any case, visit the medical insurance is needed, otherwise you risk spending money and take a scan in which in your case there was no need.

How do you do?

Approximate scheme of how computer tomography is done:

• come to the CT-diagnostic office at that time on which they were recorded - it is necessary to dress in a slight outfit from cotton, and before starting the survey, remove all items from the metal;
• with the help of the doctor, go to the table, after which the head is fixed with the belts to get the pictures to be accurate;
• the table moves to tomograph, the arch starts the rotation - this will indicate the hum and knock;
• upon completion of the scan, the table leaves from the device, the clamps are removed, and you can go on your affairs.

There are a few differences in how the procedure with contrasting and without, in particular, in the first case, before you fall on the couch, you will be introduced to you, and after the end of screening, you will recommend to drink more faster to get faster from the body. If it turns out, stay in the clinic for another 30-60 minutes so that in case of deterioration of well-being (which is extremely rare) to get qualified assistance.

Why do contrast use?

The contrasting CT-scanning of the larynx, which is most informatively, is widespread, which is most informative if the doctor suspects oncology. The introduction of iodine-containing substance an order improves the visualization of the inner cavities, "highlighting" vessels and allowing the ability to determine the location and size of tumors and metastatic neoplasms.

Before performing a study with contrasting, the doctor makes a sample to make sure allergic reactionsand also determines whether there are no other contraindications to failure to diagnose (hormonal failures, kidney dysfunction, diabetes). Even if the tumor is small, modern tomographs allow it to detect.

How long does the decryption last?

Snapshots of the larynx and other organs (for example, if CT trachea is made at the same time), an radiologist is assessed, which establishes the presence of cyst or tumors, foreign objects, injuries, reveals the foci of inflammation and makes the assumption of the causes of abnormalities from the norm. Waiting depending on the clinic and the complexity of the case can be from 40-60 minutes to one day (many centers practice issuing results the next day).

Together with the written conclusion of the doctor with a personal signature and print, you will receive a disk (or flash drive) with layers, as well as a printed set of pictures.

What is better - CT or MRI laryngeal?

Despite a certain similarity (non-invasiveness, obtaining three-dimensional images of the investigated area, etc.) at MRI and CT throat there are a number of significant differences:

• when CT screening is used x-rays (radiation is an order of magnitude less than when X-ray, but still there is a risk of negative effects with frequent surveillance), and the principle of operation of MRI apparatuses is based on the use of electromagnetic pulses;
• in price they are approximately equal, but CT is a bit cheaper;
• mAI cannot be done if you have heart pumps, electrocardiomulants and other devices;
• the number of magnetic resonance scan procedures per year is not limited.

So, what is the better computed tomography: price, speed, the ability to recognize bone damage and accessibility for people with implanted devices.

On the other hand, the study is not suitable for children and pregnant women, plus can be carried out without risk to health no more than 1-2 times within one to two years.

To determine which method will be the most informative, taking into account the testimony and contraindications, will be able to the attending physician, so before signing this or that diagnostic center, it is advisable to get to the reception to the profile specialist and get the direction.

CT Large with various diseases: video

Infectious lesions of the nasal sinuses are the usual phenomenon for the winter and spring time of the year. Many people deliberately ignore the disease and are in no hurry to contact the doctor. This may lead to a serious disease: pus and dead epithelial cells accumulate in the gamor sulk sinuses, breathing is disturbed, the temperature rises.

A preliminary diagnosis sounds like "sinusit", and the patient needs to be examined to clearly establish localization and the degree of process. CT nasal sinuses and x-rays are two universal methods that allow us to widely consider all the pathology pathologies. The procedure is recommended to do only once. Tomogram is made in two projections.

What is CT apparent nasal sinuses?

CT of the apparent sinuses of the nose is a diagnostic procedure, which is a process of layer-by-layer preparation of the human body. Through the body, X-ray radiation is carried out, the intensity of the response to which is also registered with special devices. Tomograph using a computer transforms information into a static snapshot, which can be reflected on the carrier.

Weighing advantages of computed tomography of the sinuses:

• big informativeness and diagnostic significance;
• simplicity and accuracy of research;
• it is not necessary to artificially expand the nasal passages or produce sinuses;
• relative safety survey;
• a short time required to perform the procedure;
• minimum percentage of technical problems.

Disadvantages of computer tomography:

• the inability to use during pregnancy;
• restrictions for the diagnosis of pathologies in children;
• high cost of the procedure;
• the presence of a minor amount of radiation, which can negatively affect the body of a weakened person.

Indications for computer tomography of nasopharynx and PPN

If you want to get a study as quickly as possible, contact your doctor's doctor and describe your problem. CT of the incomplete sinuses are appointed in the following cases:

Dose of irradiation

The dose of irradiation with CT of both apparel sinuses is less than 0.4 msv. Such radiation does not cause a pronounced harm and does not contribute to the occurrence of cancer. Traditionally it is believed that it is not necessary to undergo a survey for more than two times within one year: it can negatively affect the body. Looking through the procedure on video, you can make sure it is almost safe from the point of view of X-ray irradiation.

Contraindications

Computed tomography of the sinuses is prohibited in the presence of the following states:

If you are not sure that you do not feel about these groups of citizens, be sure to consult your attending physician. If there are contraindications to the procedure, it can be replaced by any other alternative options for choosing a patient and its specialist. The use of CT for spicy sinuses with pronounced contraindications can lead to a deterioration in the patient's condition and exacerbation of existing pathologies.

Procedure for computer diagnostics of the nose and the apparent sinuses

Computer tomography of the incomplete sinuses are carried out in a separate office, which is specifically designed for the survey. No preliminary preparation in the form of intestinal cleansing or injecting a contrast substance is not required during the study, so you can come to the procedure at any time of the day.

In order for the device to work as correctly and showed the accurate result, recommended to get rid of metal jewelry, buttons and hairpins at the time of the procedure. Mobile phones, tablets and other electronic devices should also be left outside the Cabinet.

A person is placed in a computer tomograph, where he has been taking place on safety instructions for a while. If the deterioration of well-being, signs of panic or anxiety occurs, the procedure must be discontinued and notify about this attending physician.

After passing the briefing, the patient is placed in the apparatus where the special device removes a series of photos in different planes. The equipment produces some noise that can be unpleasant for the patient. It is recommended to use special earplugs to prevent painful sensations.

What shows CT - decoding results

After passing the examination procedure, the patient will receive a physician of functional diagnostics together with pictures. Only a specialist who has appropriate qualifications and experience can also be engaged in the description and decoding of results. In conclusion, the procedure usually indicates information about its course, the presence of complications, pathological processes and their dynamics.

With the help of CT, the incomplete sinuses can be revealed:

After you receive the results of the survey, be sure to refer to the otolaryngologist to assign the course of therapy or set the date of the surgical operation. It must be remembered that the CT procedure can be passed with a certain interval, which should not be less than the dock appointed by the doctor. More frequent use Diagnostics can harm health and significantly worsen well-being.

Alternative to KT.

If the study of CT does not suit you for one reason or another, you can stay on other techniques (from the coordination of the attending physician) - modern medicine offers a rich choice. Options for replacing the tomography of the apparent sinuses of the nose:

• radiography of the apparent sinuses;
• magnetic resonance tomography of the incomplete moves;
• ultrasound examination;
• multispical computed tomography.

Comparative characteristics various methods Research:

Cost of examination

CT is widely used in large cities and major administrative centers. In smaller towns, villages and villages, it is not applied due to the lack of qualified specialists and specific equipment, the delivery and maintenance of which requires a lot of money.

A significant advantage of computed tomography in front of a classic X-ray examination is high informativeness and diagnostic value: CT will show much more pathologies and will not require additional methods Research.

The cost of the procedure in various cities is not very different. How much is tomography, usually tells the attending physician who will appoint the procedure. He can help with the choice of clinic. The price also depends on the thickness of the tomograph, with which the pictures, urgency and qualifications of medical personnel are taken.

The more powerful the tomograph, the better and better the pictures are obtained - so the doctor will be able to see pathology in the walls of the nasopharynx and the nose without additional procedures. On average for one X-ray photo to which the decoding is attached is to give about 5 thousand rubles. The minimum price for which you can go through the PPN procedure is 2.5 thousand rubles.

When is the nose computed tomography? The following states are indications:

• suspicion of violation of the integrity of nose bones and sinuses;
• risk of hemorrhage;
• card and brain injuries;
• frequent headaches of unknown origin;
• frequent bleeding from the nose, accompanied by an increase in blood pressure;
• suspicion of the presence of a foreign object in the nose area;
• chronic nose diseases;
• malignant tumor, the presence of purulent exudate;
• complication of infectious pathology of neighboring bodies that have passed on the nasal sinus.

What can show CT

Computed tomography of the nose sinuses allows you to see the image of layered sections of the scanned space. The study shows contours, density, structure, volume, Mineralization of PPN.

CT nose and sinuses will help evaluate the effectiveness of the therapy, if the diagnosis has been established for a long time.

On time, the pathology will help to avoid serious consequences and complications throughout the CT scan.

So, what shows the CT of the sinus nose? Through. this method The following diseases can be identified:

• at the initial stage and when chronizing the process;
• novom formulation of the mucous membranes of the nose. The study will also answer the question, malignant tumor or not;
• the cause of regular migraines;
• sphenoiditis, etmpitis;
• polyps;
• cause inflammatory process, the treatment of which does not bring effect;
• will help to visualize deformation and damage to the nose bones;
• show location foreign languages in nasal sinuses.

Advantages and disadvantages

CT of the apparent sinuses of the nose refers to high-precision methods for diagnosing nasal pathologies and its sinuses. Detailed scanning helps to understand, at what stage is the pathological process, appoint the most correct, in this situation, treatment.

What are the advantages of the CT nose and the apparent sinuses? The following advantages of this diagnostic method can be distinguished:

• high quality image of the nasal sinuses;
• high speed research;
• lack of negative impact on the body of the study;
• clear visualization of all nose formations;
• no discomfort and pain syndrome during the procedure;
• comprehensiveness - according to scan results, you can estimate the state of bone formations, blood vessels and tear canals.

But the computer tomography of the nose and the incomplete sinuses have disadvantages. They lies in contraindications. The study cannot be carried out at the following states:

• pregnancy, as CT is able to form a malformation of the fetus;
• children's age - a child cannot but move for a long time. In addition, belts cause them fear;
• allergic reactions to iodine used as contrast. But contrasts may not be applied in the study;
• lactation period;
• diseases of the thyroid gland;
• deficiency of renal, hepatic, cardiac functions;
• diabetes;
• myeloma disease.

Does prepare need

Computed tomography of the apparent sinuses of the nose does not require training if it is carried out without contrast. If contrasting is applied, then the patient must not have a study for 6 hours, it is not recommended to drink 3 hours before the procedure. It is also necessary to remove metal items, dentures.

How diagnostics is carried out

CT of the apparent sinuses of the nose is carried out as follows:

1. Specialists evaluate the status of the examined.
2. The patient explains the essence of the research method and the purpose of its conduct.
3. On the patient you wear a suit that protects the body from the effects of X-ray radiation.
4. Further, the patient is placed on the back, on the couch. Hands should be elongated along the body. The head is fixed in the headrest. May be needed to press the chin to chest and look up.
5. If necessary, the contrast is introduced. 50 ml of contrast is usually introduced into the elbow vein through the catheter. For a short time, the patient can experience heat and a specific taste. These sensations take place independently and quickly.
6. The table together with the surveyed is linked to tomograph. Further, the doctor goes to the room where the instrument is located to register and process the signals of the device. A specialist has the opportunity to communicate with the patient at the time of the survey due to the sound device.
7. During computer tomography of the nose, the table moves up or down. This is necessary to register images in various projections.
8. All examination takes 5-10 minutes. Upon completion, the patient goes home or to the ward.

Decoding results

According to the results of computed tomography of the nose, the doctor evaluates the following parameters:

• as the nasal partition and bones, which form sinuses;
• for what ways the sinuses drainage occurs;
• symmetry of the right and left sides of the nose, sinuses. This parameter will help determine the anatomical location of the bones and, if necessary, carry out surgical correction in the future;
• pneumatization of the sinuses, its degree.

The interpretation of the results of the CT nose and the incomplete sinuses can be represented in the table:

How often can I do a study

Many have the question of: how often it is possible to make CT of the nose of the nose, since with this study the patient receives a single dose of irradiation.

The radiation dose obtained from CT varies from 1 to 5 msv. The optimal scanning is not more often once every six months. If necessary, this interval can be reduced to 2 months.

In computed tomography, the patient receives greater irradiation than with x-ray and fluorography.

What is better: CT or MRI

What is better to do: CT or MRI of the sinus nose? Each method has certain readings. This or that research is prescribed, based on the intended disease.

So, with CT, bone structures are well visualized, and with MRI - soft tissues. For example, CT is suitable for detecting tumors penetrated through the stubby walls. It is also suitable for the diagnosis of samorites and frontitles of the CT, but to determine their type and detect the reason only the MRI of the nasal sinus. Magnetic resonance tomography will also help diagnose the diseases of the mucous membrane, polyps and labyrinthitis. These methods can complement each other.

CT nasal sinuses is a safe and informative study that allows you to diagnose many pathologies due to the high accuracy of the resulting image. With this method, you can determine the testimony for surgical intervention, track the effectiveness of the treatment.

Useful video about CT nose sinuses

Even the most ordinary runny nose can turn into a formidable disease. Timely identification of the problem is the key to the fact that treatment will be effective. KT nose sinus - one of the most modern methods identifying various problems in this area. What can he show and do contraindications for the use of this procedure?

A few words about CT

CT of the apparent sinuses of the nose is one of the best modern methods for the study of the nasopharynx and adjacent tissues. Thus obtained data on the state of the nose and the apparent sinuses are so accurate that only on these results, a specialist may with a high probability to raise the patient and prescribe treatment.

What does the doctor sees in the picture CT? Almost the complete condition of the area under study:

1. Facial bones, and even past injuries, cracks and fractures will be visible in the picture.
2. The condition of the soft tissues in the zone of the apparent sinuses of the nose, in particular - the gaymorette sinuses. The specialist may even understand the color of this zone in the picture, what is the quality of the tissues in this area, there is no inflammation here.
3. The state of blood vessels.
4. Channel condition.

Is it worth afraid of this procedure, because the body is irradiated? The level of exposure that man gets is extremely low. It cannot at least somehow affect the condition of the cells and tissues of the body. Similar doubts are more dangerous. The patient who is afraid to go through the CT due to irradiation, loses the precious time.

Finally, the question of the feasibility of CT is a doctor, a specialist who understands all the possible danger of late and improper diagnosis. In other words, it is not dangerous to conduct CT, but its ignoring. Even if the patient has no serious pathologies, this result makes it possible to eliminate seriously illness and more accurately diagnose the disease. The optimal period between the studies is one year, although, if necessary, the CT monitoring is carried out after 6 months.

Many people are interested, how is CT and MRI differ? With magnetic resonance therapy, the study is carried out non-X-ray, but electromagnetic waves. The image in all cases is obtained three-dimensional. The principal difference between them know only doctors. It lies in the fact that some diagnoses are better revealed on the CT, while others are on MRI. So, nervous systemBundles and muscles are more sensitive to electromagnetic waves, and therefore MRI is more often prescribed with neurological diseases, as well as for the study of joints. CT is more informative in injuries, when examining hollow organs, bones and teeth. Also, MRI has more restrictions, for example associated with the presence in the body of the patient's ear implants, a cardiac heart and other devices that cannot be removed during the procedure.

For what appoints

Cases when this procedure can be appointed, several:

• difficulty breathing;
• abundant discharge from the nose;
• nose bleeding;
• chronic runny nose that does not pass even after applying drugs;
• sore throat and ears;
• injuries of facial bones and skulls;
• toothpick, which gives into the bones of the skull;
• swelling of the sinuses;
• suspicion of the purulent process in the apparent sinuses of the nose.

What specialist directs nasophacks on CT? In the overwhelming majority of cases, this is a otolaryngologist, but sometimes the diagnosis can relate to the sphere of oncology, dentistry, ophthalmology or traumatology.

What can be revealed to CT:

1. Inflammatory process. The doctor will fix not only its presence, but also localization.
2. The presence of neoplasms, benign and malignant.
3. Foreign body. This usually concerns small patients.
4. Abscesses. On CT, you can find out if the fabric is "dead", or it still functions.
5. Damage to facial bones. Some of them can be without external injuries.
6. Polyps. They are detected very often, truth, specific surgical treatment It requires only a small part of them.
7. Congenital pathologies.

CT - a procedure that shows the state of the diagnosed zone at the moment. This means that the results of the procedure can change over time. For this reason, the CT of the apparent sinuses of the nose is carried out by the patient several times, more often - in the process of the therapeutic course. This allows you to clarify whether this therapy has an expected effect, or it is worth changing drugs and treatments.

CT is also carried out regularly in those patients who have the likelihood of a deterioration of the situation. This usually concerns the patients of oncologists, where the metastasis of cancer cells is asymptomatic, and this hardware method allows to identify the activation of the pathological process in a timely manner.

Contraindications

In what cases with the CT nose and the nasal sinuses are better to wait or try to exclude this diagnostic research method? Contraindications are:

1. Patient age up to 3 years. CT spend both infants, but only in the most serious cases. This issue should be discussed by several specialists.
2. Pregnancy. CT can be dangerous for the baby in the womb. Exposure can cause pathologies for the development of the fetus.
3. Breast-feeding. If necessary, to make CT nursing mother, it will be recommended for some time after the procedure to translate the baby to artificial feeding. Breast milk In this case, it is necessary to regularly decline and pour.
4. Heart diseases. Under a number of diseases of cardio-vascular system CT can only be carried out at a relapse, but not during the acute phase of the disease.
5. Allergy to iodine. This is the most important direct contraindication to the use of CT. CT can cause the appearance of the strongest allergic reactions, that is, the procedure itself only wishes the patient's condition. Sometimes such patients are prescribed by the reception of special preparations that allow you to better carry the introduction of contrast.
6. Diabetes. Some drugs that take diabetics are incompatible with a contrasting agent. Such patients require preliminary preparation.
7. Significant problems with liver or kidneys. With their insufficient function, it is better to abandon CT and diagnose the disease on the basis of other hardware methods and analyzes, since the contrast introduced in procedure may cause the exacerbation of diseases and the failure of these organs.

The relative contraindication may be the weight of the patient. Some devices are designed for human body weight not more than 135 kg.

How do

Before the patient procedure must be prepared. Preparation is minimal. The patient should refuse food for 5-6 hours and drink 2-3 hours before CT. This will eliminate such sideflineslike nausea, weakness, vomiting after tomogram.

Immediately before the procedure, all metal items are removed from the patient: decorations, hairpins with hair, metal plug-in jaws and removable prostheses. Metal may affect the results of computer testing and distort its results. In particular, it concerns the nasal piercing and ears, the decorations on which are located in the immediate vicinity of the studied zone.

The procedure itself passes as follows:

1. On the patient you put on a special apron that protects it internal organs From the effects of radiation.
2. The patient falls on the couch of the device and is located in a certain way.
3. The specialist includes tomograph and launches it. The apparatus at the same time hits the couch with the patient under the scanner.
4. Next occurs directly the process of computed tomography. During it, the device periodically moves and rotates a couch with a patient in different directions and at different angles. This allows you to explore the nasal sinuses in all projections.

The survey itself lasts about 15 minutes. During CT, the device publishes unpleasant loud sounds. It is not necessary to be afraid and somehow react to them. Medical staff during the procedure goes to another room protected from X-rays.

The patient's position is very serious, namely, its stillness during the procedure. Even small movements can lead to a distortion of the result. Most likely, when receiving unsatisfactory, fuzzy snapshots, the patient will be prescribed re-testing.

Result The specialist receives a few minutes after testing. They can be as submitted directly to the patient and sent to his doctor. The result is most often transmitted on information carrier - disk, where the projections of the incomplete sinuses in different planes will also be. It is also likely to print snapshots on film or paper, as well as a specialist conclusion.

The introduction of contrast

Sometimes CT is carried out without the use of contrast, although such a procedure is considered less informative. A contrast substance based on iodine allows you to get more clear pictures, which means that the doctor will be easier to determine the localization of pathology and make a diagnosis.

Contrast can be administered not only before the procedure, but also directly during it, when a specialist will already have a few native pictures.

The contrast is most often administered intravenously. Immediately after testing, the patient may feel easy weakness. Since its body was introduced in the composition of contrast, then in subsequent days it is necessary to reduce its concentration in the bloodstream and tissues. To do this, increase the amount of fluid consumed.

Nausea, tide the heat to face and body, sour or metal taste in the mouth are not causes to interrupt the procedure. What symptoms with the introduction of contrast should cause a sense of anxiety from a doctor:

• suddenly appearing the itching of the skin, visible rash on the body;
• ears, larynx, nasopharynk, even if the swelling is not visible, but only felt by the patient;
• bronchospasm;
• ensure in the throat, not related to soul diseases;
• strong drop in blood pressure.

With the emergence of these signs, a specialist may make an emergency decision to suspend the CT of the apparent sinuses and further assistance to the patient.

Computed tomography of the sinuses of the nose - a procedure that can say about this organ and adjacent tissues is much larger than the standard test results. Today, with suspected pathology in this zone, it can be done free of charge, if there are directions from the doctor. Of course, the situation with deadlines available for CT, changes from the region to the region. Only such careful attention to his health can lead to effective treatment And good well-being.
