AP severity is classified clinically into mild, moderately severe, and severe, depending on the presence and persistence of organ failure and local or systemic complications. The revised Atlanta classification divides the clinical course of AP into an early (first week) and late phase (after first week) and the clinical phase determines the role of imaging. Imaging has a limited role in the early phase. In the early phase with typical presentations of AP, ultrasound is usually the only appropriate modality and is used for the detection of gallstones. CT and MRI are appropriate in the early phase in equivocal presentations. In the late phase (or at least 48-72 hours after presentation), CT and MRI play a primary role in the imaging of patients with AP for evaluation of etiology, complications, extent of disease, intervention, and follow-up; CT is particularly useful in patients with suspected acute hemorrhage.The American College o...
