AIBL v1 structural MRI evaluation dataset
This repository contains the T1w-only AIBL v1 evaluation cohort used by
smri-fm. It has 637 participants and exactly one baseline scan per
participant.
Cohort
- 458 cognitively normal participants
- 100 participants with mild cognitive impairment
- 79 participants with Alzheimer disease
- ages 60 through 89
- 362 female and 275 male participants
Every row contains the processed T1w NIfTI, brain mask, 101 SynthSeg volumes, age, sex, and diagnosis. Sparse targets include 36-month MCI conversion; 48-month MMSE and Logical Memory slopes; and 48-month ICV-normalized hippocampal and lateral-ventricular slopes.
The locally available metadata contains PET acquisition records but not quantitative amyloid or tau results, so the dataset does not expose molecular biomarker targets.
