[What can be expected from digestive tract MRI?].

With recent technological progress, MRI can now reliably explore the digestive tract. Gastrointestinal MRI can map small intestine involvement in Crohn disease, with no irradiation in young patients. In addition, MRI provides supporting arguments for inflammatory or fibrous involvement of the intestine. MRI of anoperineal fistulae is useful in the preoperative stage to plan surgical treatment so as to reduce the recurrence rate of complex fistulae or recurring fistulae. In rectal cancer, MRI is the best examination to evaluate perirectal fascia for choosing neoadjuvant treatment.
