Will CT scan show Crohn's?

CT should be the first radiologic procedure performed in patients with acute symptoms and suspected or known Crohn disease. The ability to directly demonstrate the bowel wall, adjacent abdominal organs, mesentery, and retroperitoneum makes CT superior to barium studies in diagnosing the complications of Crohn disease.
