目的 :探讨彩色多普勒能量图 (Color Doppler energy,CDE)在经皮肝穿多弹头射频治疗肝癌中的应用价值。方法 :对 35例肝癌患者行 6 5次射频治疗 ,应用彩色多普勒超声对治疗前后肿瘤的大小及血供改变进行对比观察。结果 :35例于治疗后一周 ,15例治疗后 30天 ,7例于治疗后半年进行 B超及 CT复查。 4 7个肿块术后不同程度缩小的 31个 (6 5 .9% ) ,血流信号消失的 35个 (81.4 % )。其中 1例 2 .3cm× 2 .1cm瘤体基本消失 ,2例发现新生病灶。结论 :CDE在超声引导经皮肝穿多弹头射频治疗肝癌中 ,在术前诊断、引导定位及术后疗效的评价方面均具有重要的应用价值
Objective: To investigate the value of Color Doppler energy (CDE) in the treatment of liver cancer by percutaneous transhepatic multiple warhead radiofrequency. Methods: 35 cases of liver cancer patients underwent 65 radiofrequency ablation, the application of color Doppler ultrasound before and after treatment of tumor size and blood supply changes were compared. Results: 35 cases were treated by one week, 15 cases were treated by 30 days and 7 cases were treated by ultrasound and CT six months after treatment. Thirty-one (65.9%) with varying degrees of shrinkage and 35 (81.4%) disappeared signals of 47 masses after operation. One case of 2. 3cm × 2 .1cm tumor disappeared, two cases of new lesions were found. Conclusion: CDE plays an important role in the diagnosis of liver cancer by ultrasound-guided percutaneous transhepatic multiple warhead radiofrequency ablation in the aspects of preoperative diagnosis, guiding and evaluating the postoperative curative effect
