Abstract:

　　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: ①type I, 80.4% (123 cases); ②type II, 2.0% (3 cases); ③type III, 2.6% (4 cases); ④type Ⅳ, 2.0% (3 cases); ⑤type V, 4.0% (6 cases); ⑥type VI, 1.3% (2 cases); ⑦type Ⅶ, 1.3% (2 cases); ⑧type Ⅷ: None; ⑨type IX, 2.61% (4 cases ); ⑩type X: None. In addition, 4.0% (6 cases) was difficult to judge adopting Michels classification. Conclusions: 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.
