Eighty-seven unselected gall stones were examined radiologically and by ultrasound in vitro. No relationship of diagnostic value could be established between the amount of calcification and stone demonstration, the sonogram being influenced by the size of the stone, its surface contour and its position in the ultrasound beam. Sonography is therefore not suitable for selecting those patients on whom litholysis could be carried out. Sonography appears to be useful only in a negative way by establishing the exact size of the concretion.
对87枚未经挑选的胆结石进行了体外放射学和超声检查。钙化量与结石显示之间未发现有诊断价值的关联，超声图受结石大小、表面轮廓及其在超声束中的位置影响。因此，超声检查不适用于挑选适合进行溶石治疗的患者。超声检查似乎仅在确定结石的确切大小时有负面作用。
