| 目的 探讨螺旋CT肝双期扫描及血管三维重建对原发性肝癌动静脉瘘(AVS)的诊断价值。方法 回顾性分析了21例原发性肝癌并动静脉瘘螺旋CT肝双期扫描及其中9例血管三维重建的表现,血管三维重建方法有2种:表面遮盖成像(SSD)和最大强度投影(MIP)。结果 肝动脉-门静脉瘘(APVS,中央型)6例,肝动脉-门静脉瘘(APVS,周围型)10例。肝动脉-肝静脉瘘(AHVS)4例,混合型1例。9例肝动脉期血管三维重建均显示强化肝动脉、门静脉影及部分强化正常肝组织,图像直观,立体感强,但不能显示动静脉瘘口。根据肝癌APVS螺旋CT肝双期扫描表现,其程度分为三种:轻度(3例),中度(9例)及重度(4例)。结论 螺旋CT肝双期扫描及三维重建是诊断与评价肝癌动静脉瘘有效无创伤性方法。 |

| Objective To discuss the diagnostic value of arteriovenous shunting (AVS) of hepatocellar carcinoma by hepatic helical two-phases CT scanning and 3DCT. Methods Twenty-one cases of AVS of hepatocellar carcinoma were examined by hepatic helical two-phases CT scanning,the vessels were reconstructed by MIP and SSD techniques in hepatic helical arterial-phase. Results The AVS were demonstrated by hepatic helical arterial-phase in 21 patientes with hepatocellar carcinoma, including arterio-portal venous shunting (APVS, center) in 6, APVS (periphery ) in 10, arterio-hepatic venous shunting (AHVS) in 4, mix in 1. The enhanced hepatic artery and portal vein of AVS could be demonstrated directly by MIP and SSD during hepatic arterial-phase in 9. The extent of APVS was divided into three degree: mild APVS (n=3),moderate APVS (n=9) and severe APVS (n=4). Conclusion Hepatic helical arterial-phase and MIP,SSD were effective methods in diagnosing and evaluating AVS. |
