title: An evaluation of  75 Se selenomethionine scanning as a test of pancreatic function compared with the secretin-pancreozymin test.
abstract: The uptake of (75)Se Selenomethionine by the pancreas has been evaluated in 102 patients and compared with the secretin-pancreozymin test of pancreatic function. In groups of patients with chronic pancreatitis and cancer of the pancreas abnormal scans closely parallel the diminished exocrine secretion, especially bicarbonate output, following a submaximal dose of secretin. Thirty per cent of the group with no pancreatic abnormality have abnormal scans, though the secretinpancreozymin test is normal. Though a normal scan excludes the presence of chronic pancreatitis and cancer of the pancreas with a probability greater than 90%, an abnormal scan is found so frequently in normal subjects that it does not provide a reliable index of impaired pancreatic function.
