title: Ultrasonography and computed tomography of carcinoma of the gallbladder.
abstract: Ultrasonography and CT have been used to diagnose carcinoma of the gallbladder, since in most patients the diagnosis cannot be made through radiography alone. Ultrasonography was performed on 14 patients and CT on 7. Ultrasonographic findings are classified into four types. Frequently, there are gallstones, dilated bile ducts, or metastatic lesions in the liver or retroperitoneal lymph nodes. The diagnosis was made or suggested by ultrasonography in 84.6% of patients. Findings on CT correlated well with the ultrasonographic features.
