Answer

Ultrasonography is a quick, inexpensive, and noninvasive screening method used for the diagnosis of IBD or for repeated evaluation for complications. [68, 69, 70] Abdominal ultrasonography can rule out gallbladder and kidney stones as well as detect enlarged lymph nodes and abscesses. However, it has a steep learning curve that yields a range of sensitivity that is operator-dependent. Because of their lack of radiation exposure, ultrasonography and MRI are often preferred to CT, especially in younger patients. [65]
