[Quality criteria in pancreatic sonography ].
The quality of pancreatic sonography is determined not only by the technical equipment used and by the experience of the interpreter but also by the variable anatomical and nutritional status of the patients examined. The sonograms obtained from 211 consecutively examined patients were analyzed with regard to the quality of pancreatic imaging. Direct visualization of the parenchyma of the pancreatic head and body was found in 47%. In an additional 36%, unequivocal localization of the pancreatic area was possible by delineating the peripancreatic vessels. 17% of the studies were non-diagnostic due to over-lying intestinal gas in obese patients and cases of extensive scarring. This percentage can be reduced by a modified examination technique. The use of alternative radiological methods is, therefore, obligatory in less than 10%.
