Multiphasic examination of the stomach: Efficacy of the individual techniques in detecting 153 lesions

Multiphasic studies of the stomach were performed in 134 patients. The double-contrast, compression, mucosal relief, and full-column films obtained disclosed 82%, 65%, 62%, and 51%, respectively, of 153 lesions detected on multiphasic examinations. Detection of lesions by combinations of techniques relative to the multiphasic study was as follows: simple single-contrast and double-contrast examinations, 82%; various biphasic examinations, 89%, 91%, 97%, and 99%. The results indicate that no simple examination optimally detects gastric lesions, and that the more techniques employed, the more accurate the examination, to a point of diminishing returns
