目的评价多层螺旋CT(MDCT)显示正常和肝癌患者右膈下动脉(RIPA)显示情况.方法选择经16层螺旋CT动脉期扫描的45例原发性肝癌病人和46例正常肝脏检查者,所有图像经过MPR、VR和MIP重组并纪录.结果所有病例RIPA均得到显示(敏感性100%),RIPA起源于腹主动脉占42%,而起源于腹腔干者37%,右肾动脉起源者15%,起自胃左动脉3%,起源于肝固有动脉者2%.就RIPA不同重组方法图像质量而言,MPR和MIP优于VR,而显示RIPA的起源,MPR和VR优于MIP.正常组和肿瘤组RIPA的直径比较,肿瘤组明显大于正常组.结论 MDCT可以良好地评价RIPA,在肝癌介入治疗术前方案的制订方面有重要意义.

Objective To estimate the anatomic variation of the right inferior phrenic artery(RIPA)with multi-detector tomography(MDCT)scans.Methods 45 patients with hepatocellular carcinoma(HCC)and 46 healthy subjects were examined by contrast-enhanced CT scan(CTA)at 16-section CT scanner.Then the images were reconstructed with MPR,VR and MIP.Results RIPA were detected by CTA in all cases(sensitivity was 100%).The origin of RIPAs directly from the aorta in 42%,celiac trunk in 37%,right renal artery in 15%,left gastric artery in 3% and proper hepatic artery in 2%.For the reconstructive images quality,MPR and MIP were better than VR,but in showing the origin of RIPAs,MPR and VR were better than MIP.In compared with normal group,the diameters of RIPAs in tumor group were larger.Conclusion MDCT estimates well for the anatomy of RIPAs,which is significant for planning and embolization of extrahepatic RIPA supply in HCC.
