【摘要】 目的 应用MR早期评估经皮微波消融(MWA)肝脏肿瘤的消融范围。方法 2015年1月1日至2016年1月31日,46例肝脏肿瘤患者[55个病灶,平均直径(26.0±5.3) mm]行CT引导下经皮MWA治疗。消融后第2天,MR评估消融疗效,记录消融范围(长径×短径),与微波厂家提供的参考值进行对比分析,并对消融并发症进行记录分析(消融不足或过度)。结果 术后第2天MR显示55个病灶均成功进行MWA治疗,无严重消融后即刻并发症发生。病例分布:60 W 5 min(n=4)、60 W 8 min(n=4)、60 W 10 min(n=14)、70 W 8 min(n=4)、70 W 10 min(n=11)、80 W 10 min(n=18),对应的消融范围分别为41.3 mm×31.2 mm、52.0 mm×36.3 mm、51.5 mm×34.3 mm、52.9 mm×35.5 mm、56.8 mm×36.1 mm、64.0 mm×44.0 mm。相比参考值均偏大,其中80 W 10 min组差异最大(64.0 mm×44.0 mm比54.0 mm×37.0 mm,P<0.01)。未观察到消融不足病灶,可观察到过度消融病灶12个,主要表现为消融范围累及肝包膜或皮下肌层。结论 术后MR早期复查可用于精准评估消融范围,本研究MWA作用范围比参考值大,术前精确预估消融范围有利于肿瘤的完全消融及提高消融的安全性。
