The American College of Radiology (ACR) indicates that CT may be more sensitive than barium studies in detecting Crohn disease, owing to its ability to visualize pelvic small bowel loops, [71, 72] which are often obscured by overlapping bowel in barium studies. This and other evidence partially explain why CT has become the procedure of choice not only for helping diagnose Crohn disease but also for managing abscesses. Moreover, a growing body of literature shows that CT-guided percutaneous abscess drainage may obviate surgery.
