OBJECTIVE. We hypothesized that performing CT gastrography with the patient in the left posterior oblique (LPO) position would provide better distention and less residual fluid for the lower part of the stomach than CT gastrography with the patient in the standard supine position.

CONCLUSION. The LPO position for CT guaranteed the distensibility of and minimal residual fluid in the lower part of the stomach, thus resulting in excellent 3D CT gastrographic images.
