MASSP 2.0 Parcellation Priors

Computational priors for 35 subcortical structures derived from the AHEAD database, to be used in the MASSP algorithm. Note that the included priors are not probabilistic maps that should be used as atlases, but rather prior information to generate individual-level parcellation from quantitative MRI. Contrast supported are R1, R2star, QSM and PD ratio derived from MP2RAGEME (or MP2RAGE+ME-GRE) data at 7T, and R1, R2star, MTsat, QSM, PD derived from MPM at 3T and 7T.

基于 AHEAD 数据库计算得出的 35 个皮层下结构的计算先验，适用于 MASSP 算法。请注意，所包含的先验并非用于作为图谱的概率映射，而是用于从定量 MRI 中生成个体层面的分区信息。所支持的对比度包括由 7T MP2RAGEME（或 MP2RAGE+ME-GRE）数据导出的 R1、R2star、QSM 和 PD 比率，以及由 3T 和 7T MPM 数据导出的 R1、R2star、MTsat、QSM 和 PD。
