In 28 patient with varying degrees of biliary obstruction, the ultrasonic findings were correlated with the serum bilirubin levels and with the size of the bile ducts as measured by percutaneous transhepatic cholangiography (PTC). With ultrasound, study of the intrahepatic ducts achieved the greatest accuracy (71%); examination of common bile ducts and the gallbladder were found to be less sensitive (54 and 53%). Ultrasound proved to be very accurate in biliary obstruction, when the serum bilirubin was above 4.8 mg/100 ml (80 mumol/1).
在28例患有不同程度胆道梗阻的患者中，超声检查结果与血清胆红素水平以及经皮肝穿刺胆管造影（PTC）测量的胆管大小相关。通过超声检查，对肝内胆管的研究准确性最高（71%）；发现对胆总管和胆囊的检查敏感性较低（分别为54%和53%）。当血清胆红素高于4.8mg/100ml（80μmol/1）时，超声检查在胆道梗阻方面被证明非常准确。
