Accuracy of angiography in the diagnosis of carcinoma of the pancreas

The findings in 116 patients with verified carcinoma of the pancreas have been examined. A correct preoperative diagnosis had been made in 79 and a retrospective diagnosis was possible in an additional 30 patients. An incorrect positive diagnosis was made in 18 patients preoperatively and in 5 patients retrospectively, a common cause being localized pancreatitis. Variations in the vascular anatomy and a poor technique contributed to other errors in diagnosis.
