[Computerized tomography and magnetic resonance in the evaluation of patients with Crohn disease. Their role in the identification, assessment of extent and management of the disease].

In this study we evaluated the role of barium examinations and above all computed tomography and magnetic resonance imaging in the study of Crohn's disease. CT is most often requested for patients with suspected or known intraabdominal or pelvic abscesses. MR plays a very important role in the localization of perirectal and perianal abscesses.
