摘　　要：目的评价灌注扫描对于小肝细胞癌射频治疗后的炎性反应带及局部肿瘤进展(残留/复发)(LTP)的鉴别诊断价值。方法 72个小肝癌病灶,分别于射频治疗后第1天、第1个月、第3个月行CT灌注扫描,测量各项灌注值。结果肝癌射频后的炎性反应带与局部肿瘤进展,灌注扫描参数血流量(BF)、血容量(BV)和肝动脉灌注指数(HAP)在三个时间点具有显著性差异。结论 CT灌注扫描可以鉴别RAF治疗后炎性反应带及LTP,有助于早期发现肿瘤残留或复发。Objective To evaluate the feasibility of perfusion computed tomographic technique in distinguishing inflammatory reaction with tumor progression （residual/ recurrent） （LTP） after radiofrequency ablation （RFA） of small hepatocellular carcinoma （SHCC）. Methods All seventy-two SHCC lesions underwent perfusion CT examination on the first day, first month and the third month after kFA; and Blood flow （BF）, blood volume （BV） as well as hepatic perfusion index （HAP） were measured. Results BF, BV and HAP were statistically different in the inflammatory reaction and local tumor progression （LTP） regions on the first day, first month and the third month post-RFA CT perfusion images. Conclusion Perfusion CT scanning can distinguish post-R.FA inflammatory reaction and local tumor progression （LTP）; and may help to the early diagnosis of tumor residue or recurrence.
