Demonstration of the Normal Pancreas with Gray Scale Ultrasound
Reports in the literature have implied or indicated that the normal pancreas cannot be visualized. The reasons for this lack of visualization are: 1) the inconsistent location and appearance; 2) the increased number of echoes returning from the pancreatic structure causing it to be confused with surrounding areas and 3) technical inadequacy of previous scanning equipment. Since the normal pancreas has size and structure measurable at autopsy, it seemed logical that the pancreatic echoes were included in the normal echogram but not recognized. Taking the areas of known pancreatic location, special technique pancreatic echograms were performed and correlated with pancreatic duct cannulations in over twenty-five cases to confirm the ability to demonstrate the normal pancreas. The normal pancreas was demonstrated in over 90% of the cases.
