Early detection of acute fulminant pancreatitis by contrast-enhanced computed tomography.

Twenty-eight consecutive patients with a first attack of acute alcohol-induced pancreatitis were examined by computed tomography (CT). After a survey scan of the abdomen a rapid contrast bolus (400 mg I/kg) was given intravenously, and the contrast enhancement of the pancreatic parenchyma was measured from a consecutive series of pancreatic scans. Nine patients with a fulminant course of the disease were operated on, and haemorrhagic necrotizing pancreatitis was found in eight. In all of these the contrast enhancement was decreased or absent. Patients recovering by conservative treatment showed normal or increased enhancement. The contrast enhancement seems to constitute a useful criterion for the early differentiation of acute fulminant pancreatitis from less severe forms of the disease.
