Radiolucent gallstones frequently contain significant calcium deposits. Their detection is important in the evaluation of patients for medical gallstone dissolution treatment. The sensitivity and specificity of computerized tomography (CT) in detecting calcium was studied in 20 patients with radiolucent and in 3 with radiopaque gallstones. Although the sensitivity of the CT scan was somewhat higher than that of conventional radiography -- 46% versus 23%, respectively, for a calcium content of at least 4% -- the CT scan was negative in 4 out of 6 patients in whom the percentage of calcium in the gallstones ranged between 10 and 100. The CT scan was specific: there were no false positive results. The results of the CT scan were not related to the amount or type of calcium salt present. The study shows that the presently used CT scan of the gallbladder is not sensitive enough to select gallstone patients for medical dissolution treatment.
