* Patient fasts at least 8 hours before the exam. * Bowel distension, optimal gastric distention is a fundamental prerequisite for<unk>  data evaluation; collapsed gastric wall may mimic disease or obscure underlying pathology. * Negative oral contrast medium with effervescent granules is effective for optimal gastric distension. Data acquisition and analysis *<unk>  scanning is ideally performed on a multi-detector computed tomography (MDCT) with a thin collimation. * Data interpretation with the use of two-dimensional (2D) and three-dimensional (3D) displays for proper evaluation
