MR-enterography (MRI of Sellink)
Sellink MRI is a specialized magnetic resonance study of the small intestine. While the stomach and large intestine can be well examined by gastroscopy or colonoscopy, Sellick's MRI provides a good opportunity to assess the state of the small intestine. With this method, you can carefully examine the mucosa of the small intestine for inflammations, tumors or chronic diseases such as Crohn's disease and ulcerative colitis.
Preparation for examination
In order to properly examine the small intestine and provide the most accurate assessment of the mucosa, the intestine should be prepared for examination. Approximately 2 days before test, you should stop eating foods that are high in fat and ballast substances, such as legumes, whole grains and dairy products.
In this case, you can continue to use a sufficient amount of liquid in the form of tea, water and coffee.
The day before examination, the intestine should be thoroughly cleaned and emptied with laxatives.
On the day of examination, you should not eat anything, so that the cleaned intestine can be thoroughly inspected.
Before examination, a venous catheter is placed to the patient, through which medications will be injected during Sellink MRI. First of all you will be injected with Buscopan®, which will provide temporary relief of intestinal motility. This is necessary in order to reduce the number of artifacts arising from intestinal motility and create clear images of the intestinal tract, which will subsequently provide for a very good evaluation of study results. In addition, a contrast agent is administered into the vein of the patient, which after a while is distributed in the intestinal mucosa. Contrasting substances make it possible to better distinguish altered tissues, such as tumor tissues or tissues with signs of inflammation and healthy tissues. In addition, the MRI of Sellink allows for better consideration of structures such as vessels and tissues, since cells of different tissues differently absorb contrast substance.
Indication for examination
Sellink MRI can be performed, if there are complaints of an undefined genesis in the small intestine. It allows assessing accurately the condition of the small intestine mucosa and test it for connective tissue cleavage, for example, adhesions, inflammatory processes such as ulcers, or signs of Colitis or Crohn's disease, and for the possible presence of protrusions of the intestinal wall, as with diverticulitis .
This study also allows identifying the developmental anomalies, fistulas, abscesses, disorders of torsion of the gut during development or even stenosis.
In addition, Sellick MRI is a very good method of diagnosing malignant tumors in small intestine. Due to contrast enhancement, MRI images can well estimate their location and dimensions. This examination is also used to establish the causes of diarrhea of unknown origin, bleeding and food intolerance.
Sellink MRI is contraindicated in patients who have undergone an operation for placement of pacemaker, in-built cardio defibrillator, neuromuscular stimulator or insulin pump, or even dentures with magnetic fasteners. The doctor should inform you of known allergy or intolerance to the contrast medium.
Examination is contradicted during pregnancy.
