| 摘 要： | 阿尔茨海默病(AD)、路易体痴呆(DLB)及额颞叶痴呆(FTD)是神经退变疾病导致痴呆的几种常见类型,但DLB及FTD常被误诊为AD.结构磁共振成像(sMRI)、弥散加权成像(DWI)及氢质子磁共振波谱分析可以为AD及相关疾病的诊断及鉴别诊断提供重要的支持证据.脑萎缩模式、表观弥散系数及各向异性分数分布模式、N-乙酰大冬氨酸和肌醇在颞叶、海马、顶叶及额叶的分布模式有助于鉴别AD、DLB及FTD,并与病理改变一致. |

| Abstract: | Alzheimer's disease (AD), dementia with Lewy bodies(DLB) and frontotemporal dementia (FTD) are the main type of neurodegenerative diseases, but the FTD and DLB are always confused with AD.Structural MRI, diffusion-weighted imaging and proton magnetic resonance spectroscopy have the potential to support the diagnosis of AD and the relative disease. Brain atrophy pattern, apparent diffusion coefficient and fractional anisotropy pattern, the distribution mode of N-acetylaspartate and myo-inositol in temporal lobe,hippocampus, parietal lobe, frontal lobe could help to differentiate AD from FTD, DLB and those patterns are in accordance with the pathological changes. |
