摘要: 目的 探讨CT检查鉴别射频消融治疗兔肝VX2肿瘤后残瘤与炎症反应的方法。方法 制备兔肝VX2肿瘤模型,在射频消融治疗后不同时期行CT检查,并与病理学检查进行对比。结果 CT增强扫描发现残余瘤与炎症反应均表现为病灶周边强化带,但炎症反应在强化带外侧的肝组织亦表现为由内向外逐渐减弱的强化影,于术后第2天最强,之后逐渐减弱,2周后基本消失。结论 在射频消融治疗后一周内,CT增强扫描尚不能准确地分辨残余瘤与炎症反应带,但可以通过强化带的不同表现加以区分;术后两周,在低密度灶周边出现强化影,应考虑为残余瘤存在。

Abstract: Objective To distinguish residual tumor from inflammation after radiofrequency ablation (RFA) in hepatic VX2 carcinoma in rabbits according to the comparative study between CT and pathological findings. Methods CT and pathologic examination were performed in different stages after RFA in rabbits with hepatic VX2 tumors. Results Marginal enhancement band was showed in enhanced CT scan in both residual tumor and inflammation,but the enhancement of inflammation in peripheral liver tissues around the tumors was gradually weakened and disappeared two weeks later. Conclusion The residual tumor and inflammation could not be distinguished through enhanced CT scanning within 1 week after RFA. Low intensity lesions with peripheral enhancement 2 weeks after RFA should be recognized as residual tumor.
