air contrast enema
An enema in which two contrast agents, thick barium sulfate and air, are introduced simultaneously under fluoroscopic control, followed by multiple radiographs of the colon. This technique produces better visualization of mucosal lining lesions, such as polyps or diverticula, than barium enemas performed without air.
