超声监控超声聚焦刀治疗肝癌及疗效评价研究

目的 :评价声像图引导定位、实时监控超声聚焦刀治疗肝癌的可靠性和实用性。方法 :应用超声聚焦刀治疗原发性肝癌 5 6例 ,转移性肝癌 12例。结果 :超声引导焦点定位准确可靠。实时监控显示的回声增强是判断治疗有效的可靠指标。治疗后超声显示回声增强 ,随后中心回声减低 ,边缘回声增强 ,血供消失或明显减少 ,最终回声不均匀增强是疗效显著地特征性表现。结论 :超声能准确有效地引导焦点定位、实时疗效监控及治疗后的疗效评价

Ultrasonic Surveillance and Evaluation of the Focused Ultrasound Knife Treatment Efficiency on Hepatocellular Carcinoma

Objective:To use ultrasonogram in surveillance of high intensity focused ultrasound (HIFU)in treatment hepatocellular carcinoma(HCC).Methods:Fifty six cases with HCC were treated by focused ultrasound knife.CDFI directed focal fields,surveyed treatment and evaluated efficiency for HIFU treatment.Results:CDFI directed focal fields accurate and reliable.Real time surveillance displayed that the intensive echo was the reliable standard to evaluate efficiency.After treatment the tumor echo intensified,then gradually reduced,intensive edge echoes left,blood vessed disappeared.Irregular intensive echoes is the final evidence for evaluating the treatment results.Conclusion:Ultrasonography can exactly direct focal fields,CDFI real time is reliable for surveillance treatment efficiency of HCC.
