Evidence-Based Emergency Imaging for Non-appendiceal Acute Abdominal Pain in Adults: Pancreatitis and Diverticulitis

The chapter will present recent evidence and controversies in diagnosis of acute abdominal pain due to pancreatitis and diverticulitis. Multidetector computed tomography (MDCT) has established indications and time frames for staging severity of pancreatitis in the acute phase. Currently, the role of MRI in diagnosis of acute pancreatitis had been increasing. MRI is the modality of choice for detection of CBD stones. MDCT has high accuracy for the depiction of colonic diverticulitis, but the effect on patient management and outcome has not been well established to our knowledge.
