【摘要】 目的 对肝脏恶性肿瘤微波消融(MWA)术后MRI信号随时间的演变进行解读。方法 56例患者共56个肝肿瘤病灶,在MWA术后第2天、1个月、6个月行上腹部MRI平扫及增强扫描。观察不同时间点消融区T1WI、T2WI、DWI及增强扫描的信号变化,并判断是否存在肿瘤复发。结果 MWA后2 d,消融区在T1WI、T2WI序列表现为靶样结构,T1WI表现为中央高信号的消融坏死区与周围环绕的低信号带,T2WI表现为低信号的消融坏死区及周围环绕的高信号带;术后1个月及6个月消融区体积萎缩,T1WI及T2WI仍可见靶样结构,T1WI显示消融坏死区信号升高。增强扫描显示MWA后2 d,消融区周围存在异常高灌注,术后2 d、1个月及6个月消融坏死区均无强化。DWI序列显示消融后2 d,消融区周围反应性信号增高,术后1个月及6个月信号逐渐降低。结论 肝脏肿瘤MWA术后消融区信号变化是随时间演变的过程,对消融区MRI信号的正确解读有助于疗效判断及方案制定。
