【摘要】 共做了180例CT胆道造影(静脉法),胆道显示率达86%。对其中的正常胆道组计100例测量了左、右肝管、总管(肝总管和胆总管的合称)的近端、中段和远端的内径,得出我国成人各段胆道的正常值范围,它们分别是3.4+1.7mm,4.1±1.96mm,5.5±2.9mm,6.3±2.7mm,4.9±1.9mm。经统计学处理,总管三个部位之间有显著差异。作者提出,在CT图像上测量总管应在相对固定的部位?不同部位有不同的标准。本文还描述了胆道的正常位置和走向。讨论了CT胆道造影的方法以及造影药的浓度、剂量等问题,比较了多种方法的胆道测量,探讨了左、右肝管的粗细与体位的关系。更多还原

【Abstract】 Computed tomographic intravenous cholangiography was used to evaluate the biliary tract of 180 patients.Tne visibility rate of the bile duct was 86%.In 100 patients with normal bile duct of this series,the treasured diameters of left and right hepatic duct and those of the proximal,mid- die and distal common duct were 3.4±1.7mm,4.1±1.96mm,5.5±2.9mm,6.3±2.7mm,4.9 ±1.9mm respectively.Significance was observed between two of the three parts of the common duct. It is preferable to select a fixed portion of the common duct for mensuration,because its diameters in different parts exhibits some difference;computed tomography.更多还原
