CUPA-T2: Covariance-Aware Uncertainty Propagation and Alignment for T2 Mapping in Accelerated MRI

Quantitative T2* maps have strong potential for biomarker discovery but are limited by long scan times, rendering them impractical in clinical settings. Significant acceleration can be achieved through undersampling in k-space combined with learning-based reconstruction. However, reconstruction artifacts and noise can...

Evaluating and Calibrating Diffusion Model-derived Uncertainty for Quantitative MRI Mapping

This work systematically evaluate uncertainty maps for quantitative MRI derived from multiple inferences of a data-consistent diffusion model-based qMRI framework to indicate that diffusion model-derived uncertainty is informative for reliability assessment and selective prediction, but requires calibration for quantit...
