Scalable next-scale autoregression for medical image generation across anatomical regions

Published in arXiv preprint arXiv:2602.14512 (v3), 2026

MedVAR uses next-scale autoregression to generate CT and MRI images across six anatomical regions, with separate semantic and structural controls. The updated preprint reports training on 438,905 slices from 40 datasets and evaluates generation quality, efficiency, downstream utility, and privacy.
