The value of computed tomography (CT) in determining the cause of obstructive jaundice in 67 proved cases is described. The presence of stones, the level of obstruction, the relative size of the ringlike structures produced by the dilated bile duct, and the shape of the distal visualized ring have proved to be the most important variables. The retrospective analysis determined the correct cause in 94% of the cases. CT fulfills all goals considered important in obstructive jaundice and eliminates the need for invasive procedures in many cases.
本文描述了计算机断层扫描（CT）在确定67例经证实的梗阻性黄疸病因中的价值。结石的存在、梗阻水平、扩张胆管形成的环形结构的相对大小以及可视化远端环的形状已被证明是最重要的变量。回顾性分析确定了94%病例的正确病因。CT实现了梗阻性黄疸中所有被认为重要的目标，并在许多情况下消除了进行侵入性检查的必要性。
