supporting data for exploring diffusion techniques in dementia and MS

The dataset included several cohorts in total: 16 Alzheimer's disease (AD), 37 mild cognitive impairment (MCI), 11 subjective cognitive decline (SCD), 13 vascular dementia (VaD), 18 multiple sclerosis (MS) and 20 neuropsychiatric systemic lupus erythematosus (NPSLE) participants. Not only the raw data such as T1 weighted image were included but also the processed imgaes such as diffusion measaurements and segmentation results of T1 were also included. The dataset mainly contains the magnetic resonance imaging (MRI), T1 weighted image (T1WI) and also some processed diffution tensor imaging (DTI).
