摘要 目的观察帕金森病(Parkinson’s disease,PD)的18F-脱氧葡萄糖(18F-labeled 2-deoxyglucose,18F-FDG)正电子发射断层成像(positron emission tomography,PET/CT)显像特征,并分析利用其代谢变化特点进行辅助诊断的方法。方法收集经临床确诊的PD患者15例,对其分别进行18F-FDGPET/CT显像;利用SPM分析软件分析PD患者组的代谢模式,并统计各位患者各自的代谢改变特点。健康对照组10名,分析方法同患者组。结果与对照组相比,PD组表现为豆状核、脑干、小脑的相对高代谢,以及额叶运动前区及顶叶的相对低代谢(P<0.01)。对个体数据分析发现:15例患者中13位表现为小脑相对高代谢,8例表现为脑干相对高代谢,8例表现为壳核相对高代谢,10例表现为苍白球相对高代谢,以上区域均为观察到相对低代谢表现(P<0.01);同时12例表现为顶叶相对低代谢改变,11例表现为运动前区相对低代谢改变(P<0.01),上述两个区域均未观察到相对高代谢改变。结论与正常人群相比,帕金森患者脑部代谢改变主要表现为小脑、纹状体区代谢相对增高,同时伴有顶叶和运动前区代谢相对减低。
