Researchers have introduced DeVAR, a novel generative framework for low-dose CT (LDCT) denoising that utilizes visual autoregressive modeling. This approach conditions the generation of normal-dose CT (NDCT) images on global context tokens, progressively predicting discrete token maps. To enhance detail preservation, DeVAR incorporates a residual refiner to capture subtle anatomical structures and a dual-representation hybrid training strategy for seamless integration of continuous and discrete latent representations. Experiments on public datasets indicate that DeVAR outperforms existing state-of-the-art LDCT denoising methods in both qualitative and quantitative evaluations. AI
