Five-hour reinforcement cholecystography.

Pathologic diagnoses were reviewed in 115 patients in whom gallbladder disease was diagnosed radiogically based on nonopacification with the calcium ipodate rapid reinforcement technique. In all instances, the gallbladder was diseased. Therefore, the rapid reinforcement technique is valid and considerably reduces the time necessary to complete reinforcement cholecystography. Because the time required in only 5 h, increased convenience and decreased cost may be realized without compromising diagnostic accurracy.
