摘要:目的:阿尔兹海默症(Alzheimer’s Disease, AD)是一种常见的神经退行性疾病,海马作为记忆和认知功能的关键脑区,其亚区体积变化在AD早期诊断中具有重要意义。本研究基于磁共振成像(MRI) 及体素的形态学分析(Voxel-Based Morphometry, VBM),探讨AD患者海马亚区的体积变化及其与认知功能的相关性。方法:本研究纳入30例AD患者及30例健康对照者,采用1.5T MRI进行高分辨率T1加权扫描并采用SPM12及FSL软件完成进行VBM分析。结果:结果显示AD患者双侧海马体积较对照组显著减小,其中CA1亚区萎缩最为明显(P<0.001)且与MMSE评分呈显著正相关(r=0.72,P<0.01)。结论:本研究提示,海马亚区体积分析可提高AD诊断的敏感性,并为疾病进展监测提供影像学依据。
