Experiences with data processing to separate the images in pancreatic scanning.
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.
