摘　　要：目的 探讨64排螺旋CT肝脏血管造影在临床中的应用价值.方法 对228例患者行肝区3期血管成像扫描.重建方法为最大密度投影法（MIP）、容积再现技术（VR）.结果 在228例病例中,正常肝动脉168例,肝总动脉（CHA）来源异常10例,肝左动脉（LHA）来源异常18例,肝右动脉（RHA）来源异常8例,原发性肝癌显示肿瘤供血血管18例,正常门静脉143例,门静脉变异11例,肝内门静脉栓塞28例,肝外门静脉主干栓塞38例,门静脉显影淡28 例,未显影2例,受压移位8例 正常肝静脉（HV）128例,肝静脉变异23例,右下副肝静脉2 例,肝静脉显影淡36例,未显影18例,受压移位5例.结论 64排螺旋CT肝脏3期血管成像是了解肝脏动脉及门、肝静脉系统正常、变异及病变情况的无创、安全、方便的检查方法.Objective To study the feasibility of tri--phase angiography with 64--Mice spiral computed tomography. Methods 228 cases underwent 64--slice spiral CT tri--phase enhanced scan of whole hepatic region. All images was post--processed with maximum intensity projection{MIP）,volume rendering（VR）. Results In 228 cases,CT angiography showed 168 cases with normal hepatic artery（ HA）, 10 cases with common hepatic artery（CHA） variation, 18 cases with left HA variation , 8 cases with right HA variation ,18 cases with feeding artery in primary hepatocellular carcinoma; 143 cases with normal portal vein（ PV）, 11 cases with PV variation,28 cases with intrahepatic PV embolism,38 cases with PV embolism out of liver, 28 cases with lower density in PV, PV no showing in 2 eases,PV displacement in 8 cases; 128 cases with normal hepatic vein（HV）, 23 cases with HV variation, 2 ca ses with right infra--aecessory HV, 36 cases with lower density in HV,HV no showing in 18 cases and 5 cases with displacement of HV. Conclusion 64-- slice spiral CT tri--phase angiography is a noninvasive, safe and convenient method to display hepatic artery, portal venous and hepatic venous normal variant and disease.
