摘要
目的探讨头颅核磁共振弥散加权成像(DWI)、血管成像(MRA)对临床表现为纯运动性轻偏瘫(PMH)患者的鉴别价值。方法选择我院住院的PMH患者136例,入院后均行头颅MRI-DWI+MRA检查,根据影像学检查特征,将其分为分水岭脑梗死(CWI)、分支血管动脉粥样硬化性疾病(BAD)、腔隙性梗死(LI)3组,分别于入院当日、第7天行NIHSS评分评估患者神经功能缺损。结果治疗7d后,3组间两两比较,CWI组、LI组与BAD组比较有显著性差异(P<0.05),CWI组与LI组间无差异(P>0.05),提示BAD组进展加重。治疗前后自身比较,BAD组有显著性差异(P<0.05),提示症状进展加重。结论头颅DWI+MRA可对不同PMH患者的发病机制有效鉴别,BAD组更容易发展成为进展性脑卒中。
Objective To investigate the diagnostic value of diffusion weighted imaging（MRI）and magnetic resonance angiography（MRA）in patients with pure motor hemiparesis（PMH）.Methods 136 patients with PMH in our hospital were divided into 3groups-cerebral watershed infarction（CWI）group,branch atheromatous disease（BAD）group and lacunar infarction（LI）group according to DWI and MRA results.NIHSS scores were used to assess the neurologic impairment of the patients on the first day and on the 7th day of admission.Results After 7-day treatment,compared with BAD group,the scores of NIHSS in CWI group and LI group showed statistical difference（P〈0.05）.While there was no difference between CWI group and LI group（P〉0.05）,and syndromes exacerbated significantly in BAD group compared before and after treatment（P〈0.05）,which all indicated that condition gradually deteriorated in BAD group.Conclusion Results of Head DWI and MRA can effectively distinguish the pathogenesis in patients with difference types of PMH,and guide reasonable clinical treatment.
