RADIOLOGICAL studies permit evaluation of the gallbladder and its function with greater precision than is possible to achieve when examining any other abdominal organ.

The entire medical profession accords a remarkable level of confidence to cholecystographic findings. Thus, it appears appropriate to review the basic considerations involved in this examination as well as the significance of the findings that result from such studies.
