摘要 目的比较多发性硬化(MS)与脑梗死病灶的常规MR及磁敏感加权成像(SWI)表现,探讨SWI对脑MS病灶的鉴别诊断价值。方法 20例MS和15例脑梗死患者均经临床治疗、随访证实,均行常规MR和SWI检查。结果 20例MS患者,病灶单发7例,多发13例。T2FLAIR显示65个病灶,其中急性、亚急性期病灶26个,慢性期病灶39个;SWI显示59个病灶,病灶周边呈低信号环者42个,59个均见病灶周围伴行静脉或内部穿行静脉。15例脑梗死组均为单发病灶,急性、亚急性期病灶6个,慢性期病灶9个,SWI 9个慢性期病灶周边呈低信号环,另6个病灶表现为等或高信号。结论 SWI有助于提高对MS与脑梗死病灶病理及微循环特征的认识,对二者特别是慢性期病灶的鉴别诊断有一定帮助。
