CT定位肝癌集束电极高温射频消融术的方法和技术

目的:评价CT在集束电极高温射频消融术中的应用价值。方法:采用以色列产ELSCINT 2400ELECT全身CT对105例肝癌患者进行定位,用RF-2000射频消融仪及可伸展集束电极消融。结果:105例患者定位成功率为98.3%,总缓解率为82.8%(CR:11.7%,PR:71.1%)。结论:CT可对穿刺部位进行最佳选择,实时监测穿刺部位、电极角度、深度和病灶深部变化情况,是集束电极高温射频消融术的最佳定位监测方式。

Method and Technic for Cluster Electrode Radiofrequency Hyperthermia Ablation of Liver Cancer by CT Guiding

Objective To evaluate the applied value of CT guiding the liver cancer ablation with cluster electrode radiofrequency hyperthermia. Methods 105 cases with local lung cancer were ablated with cluster electrode radiofrequency hyperthermia by whole body CT-ELSCINT 2400ELECT. Results Success rate of 105 cases CT guiding was 98.3% and the total remission rate was 82.8%. Conclusion It is with CT that the location of percutaneous puncture can be optimally selected, and the point view and depth of the electrode can been detected anytime; also, the internal local focus can be monitored. So, the CT guiding is the optimal method to guide cluster electrode radiofrequency hyperthermia ablation for lung cancer.
