Endoscopic retrograde pancreatogram and postmortem pancreatograms were compared in 6 dogs. The main duct, branches and acini of the pancreas were opacified adequately in that order with infusion of each 1 ml of contrast medium on 4 occasions in endoscopic retrograde pancreatography, and infusion of each 0.1 ml of the contrast medium on 4 occasions in postmortem pancreatography, respectively. The two pancreatograms were almost identical to the appearance of the main duct, branches and acini. The results suggest that a postmortem retrograde pancreatogram in order to investigate the correlation between the pancreatogram and the histological findings of the pancreas.
