To assess the utility of three-dimensional (3D) hepatic helical computed tomographic (CT) arteriography as a replacement for conventional angiography in the evaluation of the arterial anatomy of patients being considered for liver transplantation.
Three-dimensional CT arteriograms were obtained in 115 patients. Seventeen patients also underwent conventional angiography, and 16 patients who did not undergo angiography underwent hepatic transplantation.
Among the 3D CT arteriograms, 106 delineated the major arteries that supplied the liver. Nine were considered technical failures. In the 17 patients with angiographic correlation, there was only one marked disagreement with 3D CT arteriography. In the 16 patients with surgical correlation, no marked discrepancies were found.
In transplantation candidates, successful 3D CT arteriography was as accurate as angiography in the assessment of hepatic arterial anatomy. It was also safer, more convenient, and more easily tolerated. Conventional CT plus 3D CT arteriography was only 25% as expensive as the cost of conventional CT and conventional angiography.
评估三维（3D）肝脏螺旋计算机断层扫描（CT）血管造影术在评估肝移植患者动脉解剖结构时替代传统血管造影术的效用。
对115例患者进行了三维CT血管造影。17例患者还接受了传统血管造影，16例未接受血管造影的患者接受了肝移植。
在三维CT血管造影中，106例清晰显示了供应肝脏的主要动脉。9例被认为是技术失败。在17例有血管造影对照的患者中，与三维CT血管造影仅有1例明显不一致。在16例有手术对照的患者中，未发现明显差异。
在移植候选者中，成功的三维CT血管造影在评估肝动脉解剖结构方面与血管造影一样准确。它也更安全、更方便，且更容易耐受。传统CT加三维CT血管造影的费用仅为传统CT和传统血管造影费用的25%。
