摘　　要：目的:评价肝脏肿瘤多层螺旋CT血管成像(MSCTA)的临床价值。方法:对30例肝脏肿瘤患者采用MSCT血管成像(MSCTA)和数字减影血管造影(DSA)两种方法,对肝动脉、门脉及重要的肝脏血管变异进行比较分析。结果:30例中MSCTA观察到12例动脉变异,包括8例肝右动脉的改变,3例肝左动脉的改变,1例腹腔干过早分叉。动脉门脉瘘4例,门脉癌栓3例。30例同时行DSA检查,动脉的数量和所有动脉血管的变异均与MSCTA的结果相一致(准确度96.7%,敏感度92%,特异度100%)。结论:MSCTA能提供有价值的肝脏血管信息,在肝脏肿瘤外科手术或介入术前可作为一种无侵袭性的首选检查方法。Objective：To evaluate the clinical value of multi-slice spiral CT angiography（MSCTA） in assessing hepatic tumor.Methods：The hepatic artery,portal vein and important vascular variations in 30 patients with hepatic tumors were comparatively analyzed by using MSCTA and digital subtraction angiography（DSA）.Results：MSCTA revealed 12 cases of vascular variations,including 8 cases of variations of right hepatic artery,3 cases of variations of left hepatic artery,and 1 case of abnormal celiac bifurcation.There were 4 cases of arteriovenous fistula,and 3 cases of portal vein tumor thrombosis.Thirty patients underwent DSA simultaneously,and the results showed that the number of arteries and the variations of almost all arteries were consistent with those revealed by MSCTA（accuracy 96.7%,sensitivity 92%,and specificity 100%）.Conclusion：As a non-invasive method,MSCTA provides useful information of liver blood vessels,and can be used before liver tumor surgery and TACE.
