[Cholecystography and ultrasound compared in the radiological diagnosis of chronic cholecystitis].

In 50 patients awaiting cholecystectomy, both cholecystography and cholecystosonography have been performed (or repeated), in order to examine the gallbladder wall implementing both examinations with the cholecystokinetic test. The results, related to the surgical, anatomical- and histo-pathological reports, show that, to detect gallbladder parietal lesions, the two studies are complementary in the diagnosis of cholecystitis: consequently, in the authors' opinion, they should always be carried out in association, with the exception of cases when cholecystography may not be possible either because of radiation protection reasons or because of jaundice. Although further experiments are required, it is suggested that the cholecystokinetic test be revalued.
