Researchers have developed Spatio-Temporal Mixture-of-Modality-Experts (ST-MoME), a novel conditional diffusion framework designed to synthesize quantitative parameter maps from dynamic contrast-enhanced MRI (DCE-MRI). This method is particularly effective when input MRI sequences are incomplete, addressing a limitation of previous approaches. ST-MoME integrates features from various MRI modalities using a spatio-temporal gating network, which generates dynamic weights to guide the synthesis process. The framework operates directly in image space with a Swin-based backbone, demonstrating superior performance on a clinical brain-tumor cohort across multiple synthesis scenarios. AI
