Existing studies regarding Parkinson’s disease classification.

Note: sMRI = structural magnetic resonance imaging, fMRI = functional magnetic resonance imaging, SPECT = single-photon emission computed tomography, PCA = principal component analysis, SVM = support vector machine, ALFF = amplitude of low-frequency fluctuations, ReHo = regional homogeneity, RFCS = regional functional connectivity strength, GM = gray matter, WM = white matter, CSF = cerebrospinal fluid, ICA = independent component analysis, BG = basal ganglia.Existing studies regarding Parkinson’s disease classification.备注：sMRI = 结构磁共振成像（structural magnetic resonance imaging），fMRI = 功能磁共振成像（functional magnetic resonance imaging），SPECT = 单光子发射计算机断层扫描（single-photon emission computed tomography），PCA = 主成分分析（principal component analysis），SVM = 支持向量机（support vector machine），ALFF = 低频振幅（amplitude of low-frequency fluctuations），ReHo = 局部一致性（regional homogeneity），RFCS = 区域功能连接强度（regional functional connectivity strength），GM = 灰质（gray matter），WM = 白质（white matter），CSF = 脑脊液（cerebrospinal fluid），ICA = 独立成分分析（independent component analysis），BG = 基底节（basal ganglia）。现有关于帕金森病分类的研究。
