Plain radiographs taken tangentially may show air in the intestine outside the abdomen, as may contrast studies of the bowel. Unfortunately, visualization of the perineum and pelvis is poor with these studies. Higher yields can be obtained with dynamic changes in position, intra-abdominal pressure, or both during the imaging studies. Better assessments of the perineum and pelvis are possible via external views of the intestine and their domain with herniography.
