* * *n.X-ray examination of the gall bladder. A compound that is opaque to X-rays is taken by mouth, absorbed by the intestine, and excreted by the liver into the bile, which is concentrated in the gall bladder. An X-ray photograph (cholecystogram) of the gall bladder indicates whether or not it is functioning, and gallstones may be seen as contrasting (nonopaque) areas within it. A fatty meal is usually also given, to demonstrate the ability of the gall bladder to contract. This technique has largely been replaced by ultrasound scanning.
* * *cho·le·cys·tog·ra·phy (ko″lə-sis-togґrə-fe) [cholecysto- + -graphy] radiography of the gallbladder.
