CT Imaging in Acute Pancreatitis
The routine use of CT imaging is not warranted as most cases of acute pancreatitis (AP) are mild and uncomplicated [1]. The primary role of imaging during the initial presentation of AP is to ascertain the diagnosis and detect pancreatic and/or extrapancreatic complications [1]. Contrast‐enhanced CT (CECT) is the gold standard for diagnosing AP. It has a sensitivity of 92% [2] and a specificity of up to 100% in detecting AP [3,4].
Contrast‐enhanced multidetector row CT (MDCT) is the gold standard for staging severity, assessing complications, and excluding other conditions that may mimic AP [1,5]. It provides high‐quality, multiphase imaging of the pancreas during a short breath‐hold.
