Diagnosis with CT on Acute Pancreatitis and Its Complication

Objective To discuss how to use CT scan technique exactly and reasonably and make diagnosis of acute pancreatitis and its complication. Methods 500ml of 20% urografin was intaken orally before scanning and 200ml of 20% urografin was intaken orally at start of scanning. Every layer was less than 25mm with 2～5mm per each. The routine scan was performed and then enhanced scan. Results The pancreas was widespread enlarged with low density, unclear contour and clouding margin when pancreatitis happened.
