摘要
目的 NTHI及CDFI评价肝癌射频治疗术早期效果。方法 应用NTHI和CDFI对行集束电极射频治疗肝癌的 3 5例患者 4 7个肿块治疗前后 1周瘤体的形态学及血供进行了观察。结果 射频术后 1周 ,3 5例患者 4 7个肿块中 3 1个体积缩小 ,9个肿块大小变化不明显 ,7个肿块较术前增大。低回声肿块变成等回声或强回声肿块 ,强回声肿块无变化或变化不均质强回声。术前 4 2个肿块可测及血流信号 ,术后 19个血流减少 ,14个完全消失。结论 NTHI和CDFI对观察射频疗效有重要的意义。
Purpose To evaluate the early phase therapy effect of hepatic cancer treated with cluster electrode radio frequency ablation by native harmonic tissue imaging (NTHI) and color Doppler flow imaging (CDFI). Methods The morphological and hemodynamics changes of 47 tumors in 35 cases hepatic cancer were investigated by NTHI and CDFI before and after one week of cluster electrode radio frequency ablation. Results In 47 lesions of 35 patients with hepatic cancer,the size of 31 lesions decreased, and 9 remained unchanged and 7 increased. The hypoechoic masses became isoechoic or hyperechoic masses. The hyperechoic masses remained unchanged or became hypo to hyperechioca before radio frequency ablation the blood singles were found in 42 cancer nodes,after radio frequency ablation the blood singles were reduced in 19 nodes and disappeared in 14 nodes. Conclusion NTHI and CDFI is a useful method to assess the therapy effect of hepatic cancer treated by cluster electrode radio frequency ablation. [
