[Diagnostic imaging of cholelithiasis--CT & MRI].
CT and MRI are inferior to ultrasound for detection of gallstones. CT and MRI however, might have distinctive features for diagnostic imaging of the cholelithiasis. The CT is sensitive, as regard with calcification of the gallstones, and able us to diagnose the composition of the gallstones manipulate the CT number. Then spiral CT, which is a new technique, is expected to improve the accuracy of detection of gallstones. Three-dimensional CT reconstruction images are useful in the sense of the anatomy of the biliary system. MRI is superior to evaluate bile juice concentration, so that it appears to make it possible to evaluate gallbladder function. Furthermore, the MRI has the potential advantage for acquisition the new knowledge relating to stone lysis.
