Researchers have developed CM-RED, a novel method for accelerating Magnetic Resonance Imaging (MRI) reconstruction using consistency models. This approach integrates a pretrained consistency model into a regularization by denoising scheme, building upon accelerated proximal gradient RED. By incorporating controlled noise injection, CM-RED enhances generative diversity and speeds up convergence, achieving high-quality reconstructions with only 4 network function evaluations. Experiments on the fastMRI knee and brain datasets show CM-RED outperforms existing diffusion and consistency model-based methods in both quantitative metrics and visual fidelity. AI
