(Second of Two Parts)Organ/Area ApplicationsGallbladderAccuracy rates for sonographic detection of gallstones have steadily increased since the description of B-scan cholecystosonography by Hublitz in 1972.74 Present methods display nonradiopaque stones 3 mm in size, and recently published correlations of sonographic, radiographic and surgical findings have established an 89 to 96 per cent overall detection rate for cholelithiasis75 76 77 78 79 80 81 82 83 equaling the results usually attributed to conventional radiographic oral cholecystography. The present level of diagnostic success derives from concurrent refinements in instrumentation, scanning technics and diagnostic criteria and has advanced ultrasonography to a major role in the evaluation of gallstones.The . . .
