The sonographic patterns of artificially produced pure cholesterol and pigment gallstones were evaluated in vitro. Cholesterol calculi exhibited a smooth echo with a relatively high beam penetration, whereas pigment calculi showed a sickle-like surface echo without beam penetration. Clinical evaluation of these criteria in 107 patients was based on correlating preoperative sonographic diagnosis with postoperative microchemical analysis of the calculi. Although small, smooth cholesterol calculi were detected via ultrasound with an accuracy of more than 90 percent, pigment calculi could not be separated and identified with satisfactory precision.
对人工制造的纯胆固醇结石和色素结石的超声图像模式进行了体外评估。胆固醇结石表现为回声平滑，且具有相对较高的波束穿透率，而色素结石则显示出镰刀状的表面回声且无波束穿透。在107例患者中基于术前超声诊断与术后结石微化学分析的相关性对这些标准进行了临床评估。尽管通过超声检测到小的、表面平滑的胆固醇结石的准确率超过90%，但色素结石无法以令人满意的精度进行区分和识别。
