1、帕金森病脑白质高信号的磁共振研究作者:陈昆明,闻彩云,陈为安,杨慧民,章圣辉,杨德业,何金彩,胡昕【摘要】目的?:探讨帕金森病(PD)患者脑白质高信号(WMH)的磁共振影像特点及其与临床分级的关系。方法:对PD和正常对照组,采用核磁共振TW1、TW2和FLAIR成像技术观察影像学表现;对帕金森病患者的年龄、病程和分级与影像学的相关性进行分析。结果:PD患者可出现脑白质的异常高信号,出现率与对照组比差异无显著性;对照组和PD组WMH阳性患者的平均年龄高于WMH阴性患者,WMH阳性PD患者的病程与WMH阴性者比差异无显著性,而WMH阳性患者的分级较WMH阴性患者高;PD患者中深部脑白质高信号
2、(DWMH)阳性者和脑室周围高信号(PVH)阳性者的年龄均较阴性者大,差异有显著性(P<0.01);DWMH阳性者的病程、分级与DWMH阴性者比差异均无显著性,PVH阳性者的病程与PVH阴性者比差异无显著性,但分级显著高于PVH阴性者。结论:PD患者的WMH与年龄、病程和临床分级有一定的相关性,WMH的病理机制有待进一步研究。【关键词】帕金森病;白质高信号;核磁共振 Abstract:?Objective:Toexplorethecorrelationbetweenwhitematterhyperintensities(WMH)andtheclinicalfeatures8ofPa

7、而引起的疾病,常见于老年人,包括CT、MRI在内的常规影像学检查往往难以有特征性的阳性发现。近年来,国外对白质高信号(whitematterhyperinten-sities,WMH)的研究较多,而对PD患者的WMH报道较少。本研究旨在观察PD患者常规MRI检查的WMH表现,以探讨其与临床表现的关系。 1??对象和方法 1.1??对象??PD患者(PD组)50例,其中男28例,女22例;年龄44~78岁,平均(60.3±11.2
