IBA100

This dataset has 100 T1 MRI scans of subjects in the age group 21-30 years from India. The dataset is gender balanced. All the adults had completed their schooling and a majority of (> 90 % ) them also had an undergraduate level education. Healthy volunteers who had no past history of head injury were selected for the study. An experienced psychiatrist examined all the volunteers and helped select only psychologically healthy subjects for the study. A clinician and an experienced neurologist examined all the scans to identify and exclude those with any structural abnormalities. Written consent was taken from all the volunteers for use of their anonymized MRI scan for research purposes. The imaging protocol was fixed to obtain scans with a voxel size of 1 × 1 × 1mm3 and a 3D matrix size of 256 × 256 × 192 . The MRI volumes were acquired using 192 sagittal cuts.
