title: Double contrast technique in the proximal stomach.
abstract: The double contrast technique is of particular value in the proximal stomach, where one is able to detect ulcers and masses not recognized on a conventional upper gastrointestinal series. Pseudotumors which may occur in the fundus with the conventional barium technique are readily resolved. When a lesion in the proximal stomach is suspected by conventional radiography, immediate use of double contrast radiography may confirm or better delineate the lesion. Double contrast examination of the proximal stomach may thus be used as a primary or immediate secondary procedure to increase radiologic accuracy.
