What is MRI enterography?
MR enterography is a special MRI scan to evaluate bowel wall features and it is usually used for small bowel, but can be used to assess both upper and lower gastrointestinal tract. It is commonly used when suspicion of Crohn’s disease arises.
The indications for an MRI Enterography are often suggestive of inflammation of the GI tract:
- abdominal pain
- abdominal cramps
- persistent diarrhea
The technique is sensitive in detecting inflammation, bleeding, intestinal tumours, ileus and other potential findings responsible for the symptoms.
Sometimes contrast (dye) enhancement is necessary, and this will be discussed with you. There are different ways to use dye in these examinations depending on what the area of concern is.
- Oral contrast (a liquid solution is prepared and administered orally)
- IV contrast (the dye, often Gadolinium, is administered intravenously via a cannula)
Contrast (dye)
Some symptoms and illnesses can be hard to detect even on a MRI scan and require injection of dye (contrast) before or during the scan.
It is particularly helpful in the following conditions:
- Tumours
- Inflammation
- Blood vessels
- Distinguishing between scar tissue and normal organ tissue
The injection is considered very safe for most and you will complete a safety questionnaire detailing your medical history before. The contrast agent (dye) is Gadolinium based and most of it is removed by your kidneys within the next day.
