目的评价超声融合CT实时虚拟导航系统引导肝癌消融治疗的临床价值.方法 2007年7月至2009年6月,对76例肝癌、125个病灶行超声融合CT虚拟导航引导下经皮射频消融治疗.其中81个(64.8%)为常规超声显示困难病灶.记录完成超声与CT融合所需时间,观察病灶局部疗效.结果完成超声图像与CT图像融合所需时间为(19.2±12.8)min(5～55 min).实时虚拟导航系统引导下经皮消融病灶完全消融率为89.6%(112/125),其中超声显示困难病灶的完全消融率为91.6%(74/81).均未发生相关并发症.结论实时虚拟导航系统引导下肝癌消融治疗是安全有效的,尤其对于常规超声显示不清的病灶更有价值.

Objective To study the efficacy of percutaneous ablative therapy for malignant liver lesions under real-time virtual guidance. Methods Percutaneous ablations were applied to 76 patients with 125 malignant liver lesions under the guidance of a real time virtual system (RVS). 64. 8% (81/ 125) lesions were undetectable on conventional ultrasound (US). The time spent on image fusion and the local treatment response were studied. Results The average time taken to synchronize the ultrasound and CT images was (19. 2±12. 8) min (range 5～55 min). Complete ablations were achieved in 86. 4% (38/44) of distinctly visualized lesions and in 91. 6% (74/81) of poorly visualized lesions on US. No treatment associated complications were found. Conclusion Ablation assisted by RVS and CT was safe and efficacious, especially for lesions undetectable by conventional ultrasound.
