The Multichannel Illinois Institute of Technology & Rush university Aging (MIITRA) atlas contains high resolution (0.5mm) T1-weighted (T1w) and diffusion tensor imaging (DTI) templates, constructed using high quality MRI data on a large (N=400), diverse, community cohort of non-demented older adults. The purpose of this work was twofold: a) to construct high resolution gray matter labels for the MIITRA atlas based on manually edited gray matter labels of the older adults included in the atlas, and b) to evaluate the performance of the new labels in labeling the gray matter of a separate group of older adults.
