【摘要】 目的 探讨MRI引导下微波消融(MWA)治疗肺转移癌的技术可行性。方法 回顾性分析2016年4月至2019年2月接受1.5T MRI引导下MWA治疗单发肺转移癌患者6例,其中原发性肝癌转移5例,直肠癌转移1例,病灶平均长径(1.83±0.95) cm(0.73~3.0 cm),在MRI引导下完成体表定位,穿刺、消融术中监控及天线调整,观察MWA术中和术后即刻MRI表现及并发症,随访复查判定消融疗效。 结果 6例患者均顺利行1.5T MRI引导下肺转移癌MWA,平均手术时间(65.8±17.0) min(52~96 min),其中4例患者行MWA术中fsFRFSE T2WI动态扫描,表现为低信号的热凝固性坏死区范围随时间进展逐渐从中央向外周扩大并覆盖高信号原病灶区。术后即刻扫描示消融灶中央呈短T1短T2信号,周边见等T1长T2信号带环绕。术后1例患者出现中等量液气胸伴肺部感染。术后平均随访时间为(7.67±4.36)个月(2~13个月),随访复查示5个肺转移癌完全消融,1个肺转移癌近血管侧病灶4个月后出现局部肿瘤进展。结论 1.5T MRI引导下MWA治疗肺转移癌是一项可行的新技术。
