Document Summary

Procedures and techniques of radiology and diagnostic imaging. Oral administration of a radiopaque contrast medium (barium sulfate) that flows into the esophagus as the person swallows. X-rays are taken as barium sulfate flows into the upper gi tract. Laxative is required after completion of the test. Bronchial examination via x-ray following the coating of the bronchi with a radiopaque substance. Allows examination of the interior passageways of the lower respiratory tract. Used less frequently due to the development of the ct scan and improved technology for bronchoscopy. Visualizing and outlining of the major bile ducts following intravenous injection of a contrast medium. Examination of the bile duct structure using a needle to pass directly into an intrahepatic bile duct to ingest a contrast medium. Procedure that examines the size of and the filling of the pancreatic and biliary ducts through direct radiographic visualization with a fiberoptic endoscope.
