目的 :应用螺旋CT扫描评价集束电极射频治疗肝癌的近期疗效 ;方法 :对 65例肝癌患者集束电极射频治疗前及治疗后一个月行螺旋CT增强扫描 ,观察治疗前后肿瘤的大小、密度、血供情况及治疗后凝固性坏死的程度 ;结果 :射频治疗后一个月 ,65例肝癌患者 78个肿块CT复查≤ 5cm的病灶体积缩小 ,密度减低 ,与治疗前相比有统计学差异 ,>5cm的病灶体积无明显变化 ,而密度减低较明显 ,70 % ( 55 78)的病灶呈完全凝固性坏死 ,增强扫描坏死区域无强化 ;结论 :螺旋CT扫描可观察肝癌射频治疗前后肿瘤的大小、密度、血供消失情况以及术后凝固性坏死程度 ,为临床治疗效果及预后提供重要参考价值
Objective: To evaluate the short-term curative effect of radiofrequency ablation of bundled electrode on hepatocellular carcinoma by spiral CT scan.Methods: Before and after treatment, 65 cases of hepatocellular carcinoma patients were treated with radiofrequency ablation of the radiofrequency electrode and one month after the treatment. The size, density, And the degree of coagulation and necrosis after treatment.Results: One month after radiofrequency treatment, the lesions of 78 lesions of 65 patients with liver cancer whose size was less than 5 cm were reduced and the density was decreased, which was significantly different from that before treatment (> 5 cm The volume of lesion did not change significantly, while the density was reduced obviously. 70% (55 78) of the lesions showed complete coagulation necrosis and no enhancement in the enhanced necrotic area.Conclusion: The CT scan can observe the tumor size, density, The disappearance of blood supply and the degree of postoperative coagulation necrosis, providing important reference value for clinical treatment effect and prognosis
