Benefits and Risks – MR Enterography

Benefits

• MRI is a noninvasive imaging technique that does not involve exposure to ionizing radiation.
• The contrast material used in MRI exams is less likely to produce an allergic reaction than the iodine-based contrast materials used for conventional x-rays and CT scanning.
• MR enterography is more reliable than x-ray imaging for correctly identifying areas of Crohn's disease involvement.
• Because MR enterography does not involve ionizing radiation, the procedure is especially beneficial for the evaluation of young patients with Crohn's disease.
• MR enterography can eliminate the need for video capsule endoscopy (VCE) and the potential complications of that procedure.

Risks

• The MRI examination poses almost no risk to the average patient when appropriate safety guidelines are followed.
• Although the strong magnetic field is not harmful in itself, implanted medical devices that contain metal may malfunction or cause problems during an MRI exam.
• There is a very slight risk of an allergic reaction if contrast material is injected. Such reactions usually are mild and easily controlled by medication. If you experience allergic symptoms, a radiologist or other physician will be available for immediate assistance.
• Nephrogenic systemic fibrosis is currently a recognized, but rare, complication of MRI believed to be caused by the injection of high doses of gadolinium contrast material in patients with very poor kidney function.
