[The diameter of main pancreatic duct on endoscopic retrograde pancreatography and the appearance of main pancreatic duct on computed tomography: a comparative study].
We have carried out a comparative study of the diameter of main pancreatic duct (MPD) on endoscopic retrograde pancreatography (ERP) with the frequency of detection of MPD by computed tomography (CT) in order to clarify the importance of MPD appearance on CT in the pancreatic and biliary diseases. The normal MPD on ERP was demonstrated by CT in a low frequency. MPD was most frequently observed in the pancreatic body on CT. The dilatation of MPD on ERP was found in both moderate and advanced pancreatitis group. However, the significant demonstration of MPD by CT was found in advanced group alone. We observed that CT finding of dilated duct correlated with that on ERP in advanced group alone.
