This case illustrates the value of the use of water (a negative contrast agent) rather than positive oral contrast agents in CT.

The patient is also scanned sooner than with standard oral preparation whilst the water remains in the stomach, in so doing distending the stomach and outlining the wall and mucosa more effectively.

In this case a degree of gastric outlet obstruction from the pylo-duodenal tumor has also made the tumor better illustrated.

Endoscopy biopsy was one of gastric adenocarcinoma.
