MRI of the sinuses: that shows better than CT scan of the sinuses

That shows an MRI of the sinuses?

One of the most advanced and high-tech medical techniques is magnetic resonance imaging. That shows an MRI of the sinuses? This high-tech device allows the user to thoroughly inspect a variety of parts of the human body and identify a variety of disorders and pathology.

Similar methods of deep diagnostics help to improve the treatment of even the most difficult of the disease.

What is MRI of the sinuses?

MRI of the paranasal sinuses can be attributed to one of the most accurate methods of research. The demand for this type of diagnostics is determined by the presence of a large number of structures type of bone in the human skull.

The method provides the possibility to visualize the details view of the skull of the patient and to identify any pathological changes. Also, MRI can be performed using x-ray methods, which include x-rays and a CT scan. It is possible to conduct an ultrasound.

Different types of inflammation and neoplastic growths is much better defined when the MRI of the paranasal sinuses. Special performance procedure is different when studying the state of the end of the ducts located between the nasopharynx and sinuses.

In that case, if the doctors have any idea about the existence of cancer tumors in okolonosovyh region, MRI of the sinuses is performed using a special contrast agents, which help pinpoint the location of malignant neoplasms.

Conducting this type of diagnosis is characterized by its duration and complexity.

After the introduction into a vein of a patient contrast agent, begins the study, which lasts about an hour. Immediately before the start of the study it is necessary to conduct a number of checks concerning the probability of whether the patient’s response allergic reactions to the contrast agent.

If you skip this step, the possible death of the patient due to the overlap of the respiratory tract resulting from allergic edema.

MRI is commonly used when there is a patient of such manifestations as:

  1. Bright allergic symptoms to certain external stimuli.
  2. The doctors suspect the patient has tumors or cysts in the sinuses.
  3. Abnormal structure of the sinuses in okolorotova space.

In addition, MRI of the nasopharynx and sinuses may be performed if there is a patient constant pain in the head with an unidentified cause.

This diagnosis is often used in situations where the patient has pain in the head in the frontal, frontal and paranasal sectors of the skull.

In some cases, defects that are detected by MRI and symptomatically manifested through noise in the ears and discomfort in swallowing.

MRI of the paranasal sinuses is performed using an ordinary scanner using special software. This kind of diagnostic checks aimed at identifying any species and forms of abnormalities in the structure and functioning of the paranasal space. Due to the presence of a large number of different bone and cartilage tissues, as well as of the mucous structures, this part of the skull require special careful consideration in the study.

What is better for sinuses — MRI or CT?

To determine the correct diagnosis it is necessary to use the best tool for exploring the space around the nasopharynx. Before carrying out such procedures it is recommended to study the advantages and disadvantages of MRI and CT.

The advantages of MRI include:

  • harmlessness, due to the lack of x-ray radiation and radiation;
  • the procedure provides for the study of detailed three-dimensional image;
  • contrastirovania the movement of blood;
  • no distorted images of the bones;
  • high differentiation of soft tissues of the body.

The disadvantages of MRI include:

  • on the resulting picture can often detect the movement of the body in the breathing process that may affect the diagnosis of diseases of the lungs;
  • the unreliability for the diagnosis of some defects of the bone tissue;
  • the high cost of the procedure;
  • the impossibility of diagnosis for patients with metal prosthesis or implants and patients with installed pacemakers.

Advantages of CT:

  • high accuracy of detecting abnormalities;
  • painless procedure;
  • accurate and detailed visualization of all tissue types;
  • low likelihood of artifacts in the image due to the movement of the patient;
  • the procedure can be performed for patients with metal prostheses and implants, and pacemakers;
  • the low cost of the procedure.

The main disadvantages of CT:

  • there is a small possibility of occurrence of cancer due to high doses of x-ray radiation;
  • the procedure can adversely affect fetal development in pregnant women, which makes it undesirable for such patients;
  • the possibility of Allergy because of the use of contrast agents based on iodine.

Given the choice between MRI or CT of the sinuses should be guided by medical advice, feasibility and financial side of the question.

By and large the performance of diagnosis that MRI, when CT is on the same level.

Using both techniques can accurately diagnose a variety of malignant or benign tumors, to identify defects in the structure of the nasopharynx, finding foci of inflammatory processes, as well as pathology of the mucous membranes.

The procedure is much cheaper than CT and MRI. For this reason, studies of the magnetic resonance type, it is necessary to conduct only in situations where there are some serious arguments from physicians.

The process of examination and determination of the final diagnosis

The procedure gives the possibility to visualize structures of the sinuses and their internal lining.

In addition, visualization amenable to the mouth of the duct located between the paranasal sinuses and nasal cavity.

This method of research helps to diagnose various inflammatory processes, neoplasms cystic nature, as well as certain abnormalities of the paranasal sinuses and cranial bones.

The method allows the physician to identify the smallest defects and pathologies that cannot be done using other diagnostic techniques.

In situations where the patient simply can’t help himself from making any movements, he proposed to take certain sedatives. The whole scanning procedure takes average 10 minutes. If not applied, the contrast, the study patient will not experience any painful or unpleasant sensations just.

The patient should not scare you that the unit itself is in the process of scanning produces a particular sound, reminiscent of crackling ice.

In the course of the procedure, the patient is in the room completely alone.

In the next room there are doctors who watch and monitor all the received images with their further study.

After the procedure the patient can return to his home or to go to work.

The cost of this procedure seriously varies from region to region and from facility policies in respect of pricing. The average cost of a MRI of the sinuses varies in the range of five thousand rubles.

After the procedure, the specialist will prepare a detailed report on the results of the study, which will be described detected deviations and pathology. A good summary of this type of research can be called when failed to reveal any abnormalities and deviations in the structure of the region of the sinuses and nasopharynx.

Procedure MRI is used to identify and diagnose such disorders and diseases in the area of the maxillary sinus, like:

  1. Various neoplastic growths malignant and benign type.
  2. Diseases of the bones tissues that arose as a result of infection such as osteomyelitis.
  3. The inflammatory process in the soft tissues of the nasopharynx.
  4. Cystic tumors and polyps inside the nose.
  5. Purulent diseases, such as sinusitis, etmoidit, sinusitis.
  6. Various pathologies of a chronic nature.
  7. Different kind of violation and defects in the structure of the nasopharynx.
  8. Different injuries and their consequences in this region of the nasopharynx.

Summary

Based on the foregoing information, it can be concluded that CT and MRI represent the kinds of medical research, giving the most complete picture of the physiological state of the body systems and organs.

Each of the methods has both advantages and disadvantages. The final decision on the appointment of a specific type of diagnostic study adopts the attending physician, based on the results of the preliminary diagnostic process of the patient and also his age, gender and some characteristics of the organism.

If the patient has no contraindications, most often the doctors prefer the MRI procedure. In individual cases, the attending physician may make the decision to parallel the two tests, because each of them provides its own information.
