摘要
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。
Purpose: To evaluate the early effect of cluster electrode radio frequency ablation on liver cancer by native tissue harmonic imaging (NTHI). Materials and Methods: NTHI was used to observe the morphological changes of 42 lesions in 30 patients with liver cancers before and 1 week after cluster electrode radio frequency ablation. Results: In 30 patients with 42 hepatic lesions, 27 lesions decreased in size, 9 remained unchanged and 6 increased. The hypoechoic masses became iso-echoic or hyperechoic masses, the hyperechoic masses remained unchanged or become hypo-to hyperechoic after the treatment. Conclusion: Radio frequency ablation guided by ultrasound is a safe and effective treatment for liver cancer. NTHI is useful in revealing the morphological change of hepatic cancer after radio frequency ablation.
