目的 :采用自然组织谐波成像技术评价肝癌集束电极治疗术的早期效果。材料与方法 :应用自然组织谐波成像 ,对行集束电极射频治疗的 30例肝癌患者 42个肿块治疗前后 1周瘤体的形态学变化进行观察。结果 :肝癌射频治疗后 1周 ,30例患者 42个肿块中有 2 7个体积缩小 ,9个肿块变化不明显 ,6个肿块较术前增大。低回声肿块变成等回声或强回声肿块 ,强回声肿块变成不均质强回声或无变化。结论 :超声引导集束电极肝癌射频治疗术安全有效 ,自然组织谐波成像图像质量高 ,能确切地评价射频术后肝癌形态学改变。
Objective : To evaluate the early effect of hepatocellular carcinoma electrode therapy using natural tissue harmonic imaging. Materials and Methods: Using natural tissue harmonic imaging, morphological changes of the tumors were observed in 42 cases of 42 patients with hepatocellular carcinoma treated by radiofrequency ablation. RESULTS: One week after radiofrequency ablation of hepatocellular carcinoma, 27 of the 42 tumors in 30 patients had a decrease in volume, 9 lesions did not change significantly, and 6 tumors increased more than before. The hypoechoic mass becomes an equal echo or a strong echo mass, and the strong echo mass becomes inhomogeneous strong echo or no change. Conclusion : The ultrasound-guided beam electrode hepatocellular carcinoma radiotherapy is safe and effective, the quality of natural tissue harmonic imaging is high, and it can accurately evaluate the morphological changes of hepatic carcinoma after radiofrequency.
