Sensitivity of ultrasonography for detecting gallstones.
Previous studies have overestimated the accuracy of ultrasonography for the diagnosis of gallstones by neglecting the systematic checking of false negative findings. In the present series only 80% of 331 cases of gallstones seen at autopsy had been detected by ultrasonography. The most frequent reason for a false negative finding was the small size of the gallstones.
