A prospective study of the accuracy in diagnosing gallstones using ultrasonography in the absence of a fluid-filled gallbladder was done over a 20 month period; 91 patients were studied. A focal echo complex with acoustic shadowing was shown to be a highly reliable criterion for diagnosing gallstones in a contracted gallbladder when (1) it was demonstrated on longitudinal, transverse, and left lateral decubitus views, and (2) the configuration of the echo complex remained the same.
在20个月的时间里,对在胆囊未充满液体情况下使用超声诊断胆结石的准确性进行了一项前瞻性研究;共研究了91名患者。当(1)在纵切面、横切面和左侧卧位视图上均显示出具有声影的局灶性回声复合体,且(2)回声复合体的形态保持不变时,该复合体被证明是诊断萎缩胆囊中胆结石的高度可靠标准。
