摘要
目的：探讨三维血流能量成像（3D—CPA）和彩色多普勒血流成像（CDFI）的临床应用价值。方法：对47例原发性肝癌的病灶进行二维、CDFI及3D—CPA的检查，比较CDFI及3D-CPA显示肿瘤瘤内或瘤周血流多普勒信号丰富程度及血管分布类型，并检测肿瘤的血流参数。结果：3D-CPA显示肿瘤血流分布丰富程度及血管分布类型与CDFI均有显著性差异（均P〈0．05），CDFI均可探及肿瘤的搏动性动脉血流，其中，收缩期峰值血流速度（PSV）为43～157cm／s，阻力指数（Iu）为0．49～0．82，大于0．65者45例。结论：3D-CPA结合彩色多普勒血流参数的检测可作为临床评价原发性肝癌血供及血管分布的常规检查方法。
Objective：To evaluate the clinical application of color Doppler flow imaging（CDFI） and three-dimensional color power angiography（3D-CPA） in dialpaosis and differential dialpaosis of hepatocellular cacinomas（ HCCs）. Methods： Forty-seven cases were examined by 3D-CPA and CDFI. The delineated amount of intratumoral and peritumoral Dopplor singal and the pattern of vascularity were compared between two methods and the blood flow parameters of tumors were detected by CDFI. Results： In forty-seven tumors, the blood flow amount of Doppler singal and the pattern of vascularity demonstrated by 3D-CPA were significandy different from that by CDFI （ P 〈 0.05） .The arterial pulsating blood flow was showed by CDFI in all tumors. Peak systolic velocity（PSV） was 43 - 157cm/s, resitance index （RI） was 0.49 - 0.82, and higher than 0.65 shown in fourty-five tumors. Conclusion： 3D-CPA integrated with the detection of the blood flow parameters can be used as a routine clinical method to evaluate the tumor blood supply and the tumor vascularity of HCC.
