In a prospective study of 174 patients referred for cholecystography, an ultrasound study (gray scale technique) was also carried out and the results of the two examinations were compared. The ultrasound examination served to demonstrate a normal gall bladder in 96% of the patients and, based on typical sonographic findings, permitted the diagnosis of cholecystolithiasis in 97%. The ultrasound examination can be carried out prior to the X-ray study as a screening method and has particular value in the work-up of patients with unclear right upper quadrant abdominal pain.
在一项对174例因胆囊造影而转诊患者的前瞻性研究中，同时进行了超声检查（灰阶技术），并对两项检查结果进行了比较。超声检查显示96%的患者胆囊正常，基于典型的超声检查结果，97%的患者被诊断为胆囊结石。超声检查可在X线检查之前作为一种筛查方法进行，对于右上腹腹痛原因不明的患者检查具有特殊价值。
