DTI2: Diffusion Tensor Imaging: more fractional anisotropy profiles and outcomes

Description

A DTI dataset used in Swihart et al. (2012). Fractional anisotropy profiles for the corpus callosum (cca) and the right corticospinal tract (rcst). Accompanying the profiles are the subject ID numbers, visit number, and Paced Auditory Serial Addition Test (pasat) score. We thank Dr. Daniel Reich for making this dataset available.
