MRI of the stomach: what shows?

 

MRI of the stomach is an accurate analysis, which shows the state of all parts of the body (the bottom, the large curvature of the body) and adjacent formations. Using this method of diagnosis revealed even in the early stages of almost all diseases of the gastrointestinal tract (benign and malignant tumor, ulcer, gastritis).

That 100% recognizes MRI of the stomach

MRI (magnetic resonance imaging) is a modern diagnostic method that is performed by the imager. The principle of operation of the apparatus is based on the interaction of radio frequency pulses with the magnetic field. Imaging of the stomach is one of the most informative methods of research in our time.

Magnetic resonance imaging will be informative for any disease of the stomach. Most often this kind of tests are needed to confirm or clarify the diagnosis. Sometimes carried out after endoscopy, fluoroscopy, CT, or in case of impossibility of their performance.

Most often, the MRI shows:

  • stomach cancer;
  • gastritis;
  • peptic ulcer disease.

It is possible to identify other diseases:

  • menetrier disease;
  • gastroenteritis;
  • polyps;
  • syndrome Mallory — Weiss.

Imaging may help in the diagnosis of complications of diseases of the stomach:

  • metastasis to neighboring tissues and organs;
  • ulcer perforation;
  • penetration of gastric ulcer;
  • perforated ulcer.

Images obtained during the analysis, show the stomach as clearly as possible, which helps to identify the presence of pathology, but also accurately determine the size, the defeat of the layers of the stomach, location and transition to the neighbouring tissues, e.g., liver and lymph nodes. This is very important in cases where the doctor has a suspicion that the ulcer was penetrable or a malignant tumor has metastasized.

Layer-by-layer examination of the body allows to diagnose the stage of the ulcer and malignant tumors helps to predict the possible development of the situation, complications and decide treatment. Accurate identification of the localization in cancer is essential for the performance of surgery and radiotherapy.

Magnetic resonance imaging in cancer

If you suspect stomach cancer specialists are increasingly turning to MRI. It is especially important for treatment to determine the stage of the disease.

At the zero stage cancer of the stomach there is very little education that are localized in the superficial layers of the mucosa. During this period the disease is not that easy to discern, but the picture of the scanner with almost absolute precision is diagnosed disease. Thanks to the zoom in many times. Therapy at this stage helps to get rid of the disease.

1 to 3 stage the tumor penetrates the wall of an organ. Can affect nearby lymph nodes. In the last phase in the images is detected not only the tumor, but multiple metastases. In this case, the MRI helps to determine the appropriateness of surgical intervention.

The analysis gives the opportunity to see diffuse thickening of the stomach wall, which allows to differentiate leiomyosarcoma, leiomyoma, and lymphoma. Also, the picture clearly emerges of gas in the abdominal cavity (if any) that forms when the ulcerative form of cancer or perforation of peptic ulcer.

Alarming symptoms

Indications for imaging of the stomach can be many symptoms which help to suspect any disease. At any pathology of the gastrointestinal tract manifestations may be similar, but in any case, the analysis must be careful not to miss the beginning of a serious disease (ulcer, cancer).

The symptoms in which should be sure to consult your doctor and moreover need to run to the hospital if you have a combination of several of the manifestations:

  • discomfort, heaviness (after a meal, on an empty stomach);
  • abdominal pain (epigastric, and above the navel), they can be of different nature and intensity (aching, sharp);
  • lack of appetite;
  • heartburn, belching;
  • rapid loss of body weight;
  • the earlier aversion to favorite foods, especially protein (meat, fish);
  • nausea and vomiting.

Also a visit to a specialist is necessary if these symptoms bother you for a long period of time, while continuously strengthening, or in your history notes family history, ie, close relatives suffered ulcer, cancer and other diseases of the gastrointestinal tract.

Contraindications

MRI is absolutely safe manipulation, which, however, has some contraindications:

  • wearing heart pacemakers;
  • the presence of metal prostheses and implants;
  • pregnancy;
  • the body weight exceeds 120 kg;
  • epilepsy;
  • the inability to keep still, for example, the unbearable pain;
  • Allergy to injected contrast agent;
  • severe claustrophobia;
  • the age of 7 (only possible with the help of anesthesia).

In any case, the absolute and relative contraindications determined by the physician.

Preparation for assay

Prior to conducting magnetic resonance imaging is recommended to refuse from eating and drinking for 6 hours. That is, the analysis should be carried out on an empty stomach. The day before manipulation should avoid foods contribute to gas production. Permitted medication, if it is impossible to refuse them for some time. For a more accurate diagnosis, as the stomach is the hollow organ which is filled with iron-containing solution. To drink a contrast agent should be gradually, in several stages.

Meanwhile, the received liquid does not stain abnormal cells, allowing them to see well in the picture as white spots on the background of uniform staining. Eating unpleasant or painful sensations are absent. The taste of iron, the solution is quite tolerable. An additional flow of contrast in Vienna.

Complications of fluid administration during and after the diagnosis is not observed. In rare cases, there is a disorder of the stomach, which passes quickly. Manipulation, on average it takes 20-30 minutes.

The continuous development of MRI gradually brings this method on the first place among methods of research of diseases of the gastrointestinal tract. Tomography is used in both the main and auxiliary method of diagnosis. It is used in almost all major diagnostic centers and clinics.
