摘　　要：目的:探讨64层螺旋CT应用于正常活体肝动脉研究的可行性,观察三维重建肝动脉的一般形态及走行规律。方法:选取行上腹部64-MSCT扫描检查的病例共153例,在智能追踪技术(smart prep)对腹主动脉腹腔干层面连续检测下,启动扫描。并将所得数据在GEADW4.2工作站进行图像处理。结果:依据Michels标准153肝动脉分型如下:①I型,占80.4%(123例);②II型,占2.0%(3例);③III型,占2.6%(4例);④Ⅳ型,占2.0%(3例);⑤V型,占4.0%(6例);⑥VI型,占1.3%(2例);⑦Ⅶ型,占1.3%(2例);⑧Ⅷ型,无;⑨IX型,占2.6%(4例);⑩X型,无。其他型,占4.0%(6例)不能归入Michels分型。结论:64层螺旋CT可以作为研究活体肝动脉形态的有效手段,三维重建能准确显示肝动脉的正常解剖类型和变异,对于活体肝动脉的研究有较好的临床应用价值。Objective： To explore the feasibility of 64-Slice spiral computed tomography on presenting and reconstructing the shape and distribution of hepatic artery of living body. Methods： 153 cases underwent the upper abdomen 64 - MSCT scan. The test of the celiac levels of abdominal aorta was performed by the smart tracking technology （Smart Prep）. The data was processed for imaging on the GE ADW4.2 workstations. Results： Hepatic arteries of 153 cases were classified by Michels standard as follows： （1）type Ⅰ, 80.4% （123 cases）; （2）type Ⅱ, 2.0% （3 cases）; （3）type Ⅲ, 2.6% （4 cases）; （5）type Ⅳ, 2.0% （3 cases）; （6）type Ⅴ, 4.0% （6 cases）; （6）type Ⅵ, 1.3% （2 cases）; （7）type Ⅶ, 1.3% （2 cases）; （8）type Ⅷ： None; （9）type Ⅸ, 2.61% （4 cases ）; （10） type Ⅹ： None. In addition, 4.0% （6 cases） was difficult to judge adopting Michels classification. Coneltmions： 64-Slice spiral computed tomography would be a useful skill to present anatomic features of hepatic artery, while 3D-reconstruction is valuable for demonstrating the distribution of hepatic artery during clinical application.
