Computed tomography in the evaluation of patients with suspected carcinoma of the pancreas

PF Sheedy 2d, DH Stephens, RR Hattery and RL MacCarty

The authors assess the efficacy of CT of the pancreas in a series of 151 patients with suspected pancreatic carcinoma. CT diagnoses were divided into four categories based on the original interpretation: "mass" or carcinoma (53 scans); normal pancreas (68 scans); normal pancreas, but another pathologic process was discovered on the CT scan (20 scans); and unsatisfactory or indeterminate examinations (10 scans). In more than 50% of the erroneous diagnoses of pancreatic carcinoma, the mass lesion seen on CT was found at surgery or angiography to be adjacent to, not arising from, the pancreas. False- positive interpretation can be avoided by improved equipment and technique and the accumulation of interpreter experience.
