肝癌彩色多普勒血流特性与动脉造影的对照研究

对４５例肝癌病人进行了彩色多普勒血流成像（ＣＤＦＩ）与动脉造影（ＤＳＡ）的对照研究，结果表明：小肝癌以瘤周的搏动性血流为主，大肝癌则以复合血流占优势，复合血流病灶ＤＳＡ显示比单一血流病灶的血管含量高（Ｐ值＜０．０１）。在血管含量较多的肿瘤，其收缩期峰值血流速度明显高于血管含量中等或血管含量偏少的肿瘤。另外，肿瘤直径越大，Ａ－Ｖ瘘的出现率越高，并且肿瘤血管的最大血流速度也随肿瘤的增大而增高。

Comparative Study of Flow Characteristics in Liver Cancer by Color Doppler and Angiography

Forty-five patients with liver cancer were studied by color Doppler flow imaging(CDFI) and the results were compared with hepatic artery angiography, peritumoral pulsatile flow was identified as the most dominant pattern in small liver concers. In larger liver concers, combined pattern predominated, Lesion with combined pattern of flow had a higher degree of vascularity on angiography than those with single pattern of flow(P<0.01). The peak systolic flow velocities in the highly vascular tumors were significantly higher than those in moderately and less vagcular ones. Larger the diameter of tumor, the higher was the incidence of A-V shunt. The peak systolic flow velocity increased with the enlargement of tumor.
