Stomach outline visualization in gastrointestinal transit studies using scintigraphy.

Abstract

A major disadvantage of gamma scintigraphy in gastrointestinal transit studies is the inability to provide adequate delineation of anatomical details. As an aid to the important requirement of outlining the stomach to ensure accurate quantification of the time at which material empties from this organ, a new technique is described, using short half-life 81mKr gas to provide clearer identification of the stomach outline and position.
