肝癌射频消融后的影像学评价

射频消融术(RFA)是肝癌综合治疗中的一项重要手段,尤其是对小肝癌的治疗,临床疗效较好。由于RFA治疗范围的局限,术后常有肿瘤病灶的残存或出现复发。因此,准确地评价RFA术后疗效非常重要。本文综述了不同影像手段对RFA治疗肝癌的疗效评价,同时讨论不同评价方法的优劣,以冀为采取合理的影像手段,做出正确的临床处理提供参考。

Imaging evaluation of liver cancer after radiofrequency ablation therapy

Radiofrequency ablation has been an important means of the comprehensive therapy for liver cancers,especially for the treatment of small hepatocellular carcinomas.Radiofrequency ablation has already showed encouraging clinical effects.However,due to the limitation of ablation extent the remnants of tumor lesions or the recurrence of tumor are often seen.Therefore,it is very important to accurately evaluate the curative effect of radiofrequency ablation.This paper aims to summarize the evaluation of curative effect of radiofrequency ablation with different imaging methods,and to discuss the advantages and disadvantages of these different imaging methods in order to provide a correct reference for taking reasonable imaging means to help make the proper clinical treatment.(J Intervent Radiol,2012,21: 75-78)
