Real-time and conventional articulated-arm gray-scale static-mode scanning were performed on 100 patients in a prospective study to determine the complementary or duplicative roles of these two ultrasound modalities in the confirmation of clinically suspected cholelithiasis. Twenty-five abnormal findings were documented ultrasonographically, including 21 cases of cholelithiasis (12 confirmed by oral cholecystography and/or surgery), two cases of biliary sludge, one case of a gallbladder polyp, and one case of a probable blood clot. There was no instance of gallbladder lumen nonvisualization. Except in one case (that of a 420-pound patient), real-time ultrasonography documented all the gallbladder abnormalities shown by the articulated-arm static scans. In two cases, one corroborated by oral cholecystography, cholelithiasis was documented by real-time and not by static-mode ultrasonography. In most cases, real-time ultrasonography can be used to document the presence of cholelithiasis and obviate the need for conventional articulated-arm static-mode scanning.
在一项前瞻性研究中，对100例患者进行了实时和传统关节臂灰阶静态模式扫描，以确定这两种超声检查方式在确诊临床疑似胆石症方面是互补还是重复。超声检查记录了25例异常发现，包括21例胆石症（其中12例经口服胆囊造影和/或手术证实）、2例胆泥、1例胆囊息肉和1例可能的血凝块。未出现胆囊腔不可见的情况。除1例（体重420磅的患者）外，实时超声检查记录了关节臂静态扫描显示的所有胆囊异常。在2例经口服胆囊造影证实的病例中，实时超声检查记录了胆石症，而静态模式超声检查未记录到。在大多数情况下，实时超声检查可用于记录胆石症的存在，从而无需进行传统的关节臂静态模式扫描。
