Title: Evaluation of anatomic variations of the hepatic arteries with multi-slice CT angiography
Abstract: Objective To evaluate anatomical variations of hepatic arteries using multi-slice computed tomographic angiography(MSCTA).Methods A total of 500 patients underwent 3-phase enhanced CT and the raw data of artery-phase were reconstructed including multiphase planar reformation(MPR),maximum intensity projection(MIP) and volume rending(VR) techniques.According to Michel's classification,the anatomy of hepatic artery was evaluated.Results A total of 200(40.0%) hepatic artery anatomic variations was detected in 500 patients.The cases were classified as Michel′s type Ⅰ in 300 cases(60.0%),type Ⅱ in 40 cases(8.0%),type Ⅲ in 42 cases(8.4%),type Ⅳ in 10 cases(2.0%),type Ⅴ in 28 cases(5.6%),type Ⅵ in 30 cases(6%),type Ⅶ in 18 cases(3.6%),type Ⅷ in 6 cases(1.2%),type Ⅸ in 8 cases(1.6%),and type Ⅹ in 6 cases(1.2%).There were 12 hepatic artery anatomic variations which could not be included in the Michel's classification.Conclusion MSCTA as a non-invasive method could effectively evaluate anatomic variations of hepatic arteries.
