AA-ViT: Anatomically Aware Vision Transformer with Structural and Frequency Guidance for Contrast Enhanced Brain MRI Synthesis
AA-ViT synthesizes contrast-enhanced brain MRI from pre-contrast T1/T2/FLAIR using edge-aware dense encoding and frequency-guided losses, achieving higher PSNR/SSIM than four baselines on BraTS2021.
