Abstract
In a series of patients suspected of having pancreatic disease both ultrasound and computerized tomography (CT) were performed. The diagnosis was confirmed in 50 patients. CT visualized the pancreas in all 50 (100%) whereas ultrasound was successful in 40 patients (80%). The ultrasound failures were due to bowel gas anterior to the pancreas. The overall diagnostic accuracy was 84% for CT and 64% for ultrasound; however, in those cases where ultrasound successfully detected the pancreas the diagnostic accuracy was 80%.
