duodenography /do̅o̅′ədənog″rəfē/ [L, duodeni, 12 fingers; Gk, graphein, to record] , the radiographic examination of the duodenum and pancreas. It usually requires drug-induced paralysis of the duodenum to prevent peristaltic activity, use of a double-contrast medium, and maximum distension with the contrast medium so that the duodenum presses against and outlines the head of the pancreas. Also called hypotonic duodenography.
