This is a local derivative of medarc/adni-mini-v1-3.
It preserves the v1.3-r2 row order, metadata columns, labels, image geometry,
and float32 values inside the brain. The only image change is:
image[synthseg_dseg == 0] = 0.0
The brain mask is therefore defined strictly as nonzero labels in the matching
SynthSeg discrete segmentation.
