摘要
目的探讨螺旋CT评价小肝癌射频消融术的疗效及随访过程的价值。方法对28例小肝癌患者行RFA治疗,分别于治疗后1个月、3个月及6个月行螺旋CT随访。结果术后1个月CT显示25例肿瘤完全坏死,其中19例肝动脉期与门静脉期均无强化,6例动脉期边缘薄环状强化;3例发现肿瘤残留表现为动脉期边缘结节状强化。25例肿瘤完全坏死者术后3个月及6个月CT随访示毁损灶较术后1个月缩小,无强化,其中2例术后6个月发现肝内异位复发。结论射频消融是小肝癌一种有效的治疗方法,螺旋CT双期增强扫描是评价其疗效及随访的有效影像检查手段。
Objective To assess the value of MSCT in the follow-up of patients with small hepatocelluar carcinoma （sHCC） treated with RFA. Methods Twenty-eight patients with sHCC underwent MSCT scanning 1, 3 and 6 months after RFA. Results One month after RFA, 25 tumors were completely necrotized, among which 19 presented no enhancement on dual-phase contrast CT scans and 6 showed thin ring shaped enhancement on artery-phase contrast. Three cases with residual tumor manifested as nodular enhancement in margin of lesion. Three and 6 months after RFA, all 25 tumors, which were completely necrotized, became small and presented no enhancement. New tumors were found in the liver in 2 cases six months after RFA. Conclusion RFA is an effective therapeutic method for sHCC, and MSCT dual-phase enhanced scanning is a good way for evaluating the curative effect and follow-up.
