The Contrast Medium
During the second world war, barium was the generally accepted contrast medium for examination of the small intestine. The 40-year-old custom of mixing nutrients with the contrast medium was abandoned since this appeared to be the main reason that good mucosal patterns could not be obtained. The importance of fine demonstration of anatomical detail had become paramount since the morphological examination of the small intestine had replaced the functional examination. The omission of nutrients, however, did not improve the characteristics of the contrast medium to an extent such that it could be regarded as ideal and satisfactory for everyone.
