title: Computed tomography of the pancreas: the use of intravenous contast to define the dorsal surface of the pancreas.
abstract: After a non-selective review of 80 abdominal CT examinations, it was found that the use of intravenous contrast markedly improves the recognition of the superior mesenteric vein and the splenic vein. These veins lie adjacent to the posterior surface of the pancreas. When the pancreas is poorly seen due to inadequate retroperitoneal fat, when pancreatic size is borderline, or when pancreatic ductal obstruction is suspected on scans prior to intravenous contrast administration, the use of contrast may resolve the uncertainty.
