MRI for the diagnosis of Crohn's
What does it consist of?
To carry out the test, you must remain stretched out on your back with your head resting on a cushion and a radiologist will administer a contrast medium orally to mark the area to be studied. Next, the stretcher will move until the abdominal area is in the center of the resonance equipment. The test can last from 20 to 45 minutes. During this time, you will have to remain as calm as possible, since the taking of images is not continuous, but different image planes are made. Once finished you can continue with your daily life as normal.
Cases in which it is recommended
Who is it for?
MRI for the diagnosis of Crohn’s is mainly indicated in the following cases:
- Patients with symptoms of diarrhea, abdominal pain, weakness, weight loss and lack of appetite.
- People suffering from intestinal obstruction and bleeding in the stool.
- Patients with a family history of Crohn’s disease or another type of inflammatory bowel disease (IBD).
The characteristic symptoms that make one suspect the presence of this disease are highly variable depending on the area where it is focused, so it is important to consult with a specialist in gastroenterology to obtain an accurate diagnosis.
How should you prepare?
First of all, you must go fasting for a minimum of 6 hours. Next, they will administer a contrast medium orally to mark the area to be studied. Subsequently, you should be stretched out in the MRI for 20-45 minutes, remaining as calm as possible during the entire examination.
