This is a 1976 lecture at the University of Texas System Cancer Center given by Dr. Harvey M. Goldstein, Assistant Professor of Radiology, on double-contrast examinations of the gastrointestinal tract. Dr. Goldstein believes that double-contrast techniques are not difficult to perform and may be conducted by any interested radiology department. He also asserts that the diagnostic capabilites of GI tract radiology are extended by using these techniques. This is demonstrated by a lengthy slideshow that shows patients receiving treatment, and views of internal organs, carcinoma, ulcers, lesions, and other disorders, with an emphasis on how the double-contrast reveals more information. A barium swallow is used, and an anti-foaming agent and gas preparation are added when performing an air contrast exam on the stomach, duodenom, and colon.
