1. We classically would distend the stomach with 750cc of 3% Hypaque. We now routinely use 750-1000 cc of water. This allows better evaluation of the gastric wall and definition of tumors, etc.
2. Another reliable protocol is 5mm collimation and a pitch of 1 and reconstruction of data at 5mm intervals. This is primarily as a screening mode.
