title: Ileocolic intussusception: new sign on the supine cross-table lateral radiograph.
abstract: The ability to detect ileocolic intussusception on the supine cross-table lateral radiograph of the abdomen in infants was prospectively evaluated in 12 cases (including two recurrences) over a 2-year period. The intussusceptions (including one recurrence) were directly depicted on five radiographs as a homogeneous water-density mass producing a convex interface with bowel gas at the anterior part of the abdomen. In another four patients, the intussusception produced an inappropriate craniocaudal separation of gas-filled bowel loops in the upper part of the abdomen, caudal to the liver shadow. The intussusception was prospectively recognized on the supine cross-table lateral radiograph in nine of 12 cases.
