Diagnostic informative value and radiation exposure in retrograde cholangiopancreatography and computerized tomography of the pancreas

A comparative analysis of the diagnostic value of retrograde cholepancreartography (RCPG) and computed tomography (CT) in 50 patients with chronic pancreatitis and pancreatic tumors and comparison of radiation exposure of a patient during the use of these methods of X-ray examination was carried out. CT was shown to be a more informative method, particularly in the diagnosis of chronic pancreatitis. However, the results obtained with CT, were not specific enough to make convincting differential diagnosis between tumorous and inflammatory processes. In parallel with it radiation exposures the patients were subjected to, were assessed using an original method with thermoluminescent dosimeters. It was established that tissue doses, on the whole, were larger in RCPG than in CT, the difference-being determined by the distinctive features of both methods and the duration of the scopic component in pancreatography
