Using computer-assisted scintillation camera imaging bile duct dynamics was studied in 28 patients with a nonvisualizing gallbladder due to acute cholecystitis. Postoperative repeat studies were carried out in 8 of the 28 patients. In half of the studies three accumulations of activity were evident on the 60 added 1-min views. These three accumulations were interpreted as corresponding to the biliary tree. An explanation for the separation of the activity into three depots, is proposed. Analysis of the time-activity curves of the accumulations showed an irregular exchange of activity, suggesting intracholedochal movements of bile. Passage of bile from the common duct into the duodenum was observed 1-7 times during the 1-h studies. In most studies the bulk of the activity was caught by an antegrade peristaltic wave as soon as it left the duct. The activity was then transported rapidly in a medial direction. This finding suggests that relaxation of the sphincter occurs in phase with duodenal peristalsis.
利用计算机辅助闪烁照相机成像技术，对28例因急性胆囊炎导致胆囊不显影的患者的胆管动力学进行了研究。28例患者中有8例进行了术后重复研究。在半数研究中，在60次加1分钟的观察中可见三次放射性聚集。这三次聚集被解释为对应于胆管树。本文提出了将放射性分为三个储存库的解释。对聚集物的时间-放射性曲线分析显示放射性交换不规则，提示胆汁在胆管内运动。在1小时的研究中观察到胆汁从胆总管进入十二指肠1至7次。在大多数研究中，大部分放射性一旦离开胆管就被顺行蠕动波捕获。然后放射性迅速向内侧运输。这一发现提示括约肌的松弛与十二指肠蠕动同步发生。
