摘要目的：探讨肝小静脉闭塞病的MRI影像特征。材料和方法：2例因服用“土三七”致肝小静脉闭塞病的MRI表现，并复习相关文献。结果：本组2例均为男性，均表现为大量腹水，肝脏体积增大，T2WI肝脏多发片状高信号，门静脉周围水肿，表现为沿门静脉走行高信号影，T1WI同反相位（in phase-out of phase）两者信号改变无明显差异，表现为肝脏多发片状低信号，DWI肝脏信号未见明显弥散受限。动态增强扫描表现为动脉期肝脏轻度不均匀强化，静脉期及延时期不均匀强化逐渐明显，呈“花斑”状、“地图”状改变。肝静脉变细，显示不清，下腔静脉变扁、变小。2例同时合并胆囊壁水肿。结论：肝小静脉闭塞病的MRI表现有一定特征，结合口服“土三七”病史、相关临床表现、实验室检查，可作出肝小静脉闭塞病的诊断。
