Researchers have developed a new method called Piecewise Dynamic Diffusion Regularization (PDDR) to reconstruct cardiac cine MRI images more efficiently and effectively. This technique integrates a spatiotemporal diffusion model as a generative prior within a variational reconstruction framework. PDDR utilizes dedicated spatial and temporal layers to capture anatomical structures and cardiac motion, applying the dynamic prior in a piecewise manner for processing long real-time sequences. Experiments show that PDDR surpasses existing methods in quality and computational speed for free-breathing, real-time cardiac MRI. AI
