| 目的 探讨16层螺旋CT肝脏多期血管成像方法及其临床价值。方法 对70例肝脏多期增强扫描患者,行肝动脉期、门静脉期双期血管成像,采用最大密度投影(MIP)、容积再现技术(VRT)、表面遮盖显示(SSD)重建技术,分析三种重建方法对肝动脉、门静脉系统以及肝肿瘤血管性病变(HTVPC)显示情况。结果 肝动脉期CT血管造影术(CTA)对二级肝动脉、三级分支以下肝动脉、肿瘤供血动脉及肿瘤血管的显示率分别约90%、69%、90%、69%。MIP与VRT对二级肝动脉分支及肿瘤供血动脉显示的差异无统计学意义(P＞0.05),对三级以下肝动脉分支及肿瘤血管的显示有显著性差异(P<0.05),以MIP显示率为高。门静脉期CTA可显示正常肝内门静脉5~6级分支。肝癌肝动脉-门静脉瘘发生率约13.9%,门静脉癌栓发生率约58%,以MIP显示最佳。结论 16层螺旋CT肝血管成像是了解肝动脉、门静脉系统状况及肝肿瘤血管性病变的无创性血管成像技术,以MIP及VRT价值较大,可为外科手术及介入术前提供重要信息及指导作用。 |

| Objective To discuss the feasibility and clinical value of multi-phase angiography of the liver with 16-slice spiral CT. Methods The hepatic arterial phase and portal-vein phase CT angiography were performed in 70 patients. Maximum intensity projection (MIP), volume reconstruction technique (VRT) and surface shaded display (SSD) were used to reconstruct the liver vessels, and the displaying status of hepatic artery, portal vein system and the hepatic tumorous vascular pathological changes (HTVPC) were analyzed. Results In hepatic-artery phase CT angiography (CTA), the displaying rates of the grade-2 hepatic arterial branches (HABs), grade-3 and sub-grade-3 HABs tumor blood-feeding artery (TBFA), intra-tumor tumor vessels (ITTVs) were 90%, 69%, 90%, 69%, respectively. Between MIP and VRT, there were no significant differences (P>0.05) in displaying grade-2 HABs and TBFA; but there were significant differences (P<0.05) in displaying sub-grade-3 HABs and ITTVs, and MIP was superior to VRT. In portal-vein phase CTA, MIP and VRT may showed equally well the grade 5-6 branches of normal intra-hepatic portal vein. The rate of hepatic arterioportal fistulae (HAPF) was about 13.9%, portal vein thrombosis was about 58%, and MIP showed better than VRT. Conclusion 16-slice spiral CTA is a non-invasive technique for observing hepatic arteries, portal vein system and HTVPC, which can provide important information and guidance effect for surgical operation and interventional therapy. |
