Radiological concepts of cholecystokinin cholecystography.

Cholecystokinin-cholecystography originated in Stockholm in 1955. At the present time the radiological procedure is conducted under supervision of medical research teams in the United States. The cholecystokininpancreozymin preparation is imported for clinical investigation under "Investigational Drug" regulations. Dr. Donald Hanscom, gastroenterologist, who is conducting clinical investigations in the Midwest, submitted radiographs, publications and evaluations from his files for this manuscript. This gastrointestinal hormone "squeezes out a diagnosis" as it is observed fluoroscopically. Dr. LeRoy B. Garbe, radiologist, evaluates these findings in the cases presented. The effects of cholecystokinin on the contrast-filled gall bladder give enhanced diagnostic information for the patient suffering with chronic cholecystitis and cystic ductitis.
