目的 探讨螺旋CT对经皮穿刺射频治疗肝癌估计预后的意义。方法 31例肝癌者与术前及术后 1周行螺旋CT扫描 ,其中 1 0例 1月后再次行螺旋CT检查。结果 31例治疗 1周CT检查可见肿瘤内低密度区增大 ,仅肿瘤边缘可见有强化 ,80 %的病人瘤体缩小在 30 %以上 ;1月后 1 0例复查瘤体缩小在 40 %以上 ,瘤体内低密度区进一步扩大 ,与术前相比瘤体内血供消失。结论 多弹头射频治疗肝癌时 ,螺旋CT对了解术前肿瘤大小 ,以及术后肿瘤坏死程度、血供消失情况有重要价值 ,对于估计预后有指导意义
Objective To investigate the significance of spiral CT in estimating the prognosis of hepatocellular carcinoma by percutaneous radiofrequency. Methods Totally 31 patients with hepatocellular carcinoma were examined with spiral CT before surgery and 1 week after surgery. Results 31 cases of 1-week CT examination showed that the low-density intra-tumor area increased, only the edge of the tumor can be seen enhanced, 80% of the patients reduced to more than 30% of the tumor; 1 month after the review of the tumor shrinkage of more than 40% , The tumor in the low-density area to further expand compared with the preoperative tumor in the body disappeared. Conclusion Multi-warhead radiofrequency treatment of liver cancer, spiral CT to understand the size of the tumor before surgery, as well as the degree of tumor necrosis, blood supply and disappear has important value for the estimation of prognosis
