Experiences with data processing to separate the images in pancreatic scanning

Abstract

SUMMARY In many subjects, overlap of the image of the pancreas by the liver image makes clear delineation of the pancreas uncertain. A dual isotope technique was evolved with a ratio substract system. Experiments in vitro with a phantom liver and pancreas successfully erased the liver image from the final printout. In vivo, however, the results were in many cases unsatisfactory. A detailed statistical analysis of the data has provided an explanation for these differences.

Radioselenium in Duodenal Aspirate as an Assessment of Pancreatic Exocrine Function

“…Although there have been a number of studies of selenomethionine metabolism in man (Awwad et al, 1966;Charlesworth et al, 1970), the appearance of the radioactive label in human duodenal juice after the intravenous injection of 75Se-selenomethionine has not been reported before. The present studyinvestigates the appearance of 7 5Se in duodenal test meal aspirate as a measure of pancreatic enzyme secretion and hence of pancreatic exocrine function.…”
