Abstract:Ultrasound and computed tomography (CT) are both relatively new techniques for evaluating gallbladder and biliary disease. Ultrasound is more sensitive than CT for detecting the presence of gallstones because of partial volume averaging errors which occur with CT. Both modalities are sensitive methods of differentiating jaundice due to intrahepatic disease from extrahepatic obstruction. However, CT should not be considered a screening test at the present time and should be reserved for selected cases where ult… Show more
“…Although CT is not superior to ultrasound in the evaluation of gallstones [4], CT is valuable for diagnosing gallbladder diseases [1,[5][6][7][8][9][10]. On abdominal CT study, gallstones may be incidentally detected in some cases.…”
Six cases of low-density gallstones with computed tomographic appearances are reported. On abdominal CT study, a gallstone may be identifiable not only as a high-density area but also as a lowdensity one.
