MPFlow: Multi-modal Posterior-Guided Flow Matching for Zero-Shot MRI Reconstruction

arXiv:2603.03710v3 Announce Type: replace-cross Abstract: Zero-shot MRI reconstruction relies on generative priors, but single-modality unconditional priors produce hallucinations under severe ill-posedness. In many clinical workflows, complementary MRI acquisitions (e.g. high-quality structural scans) are routinely available, yet existing reconstruction methods lack mechanisms to leverage this additional information. We propose MPFlow, a zero-shot multi-modal reconstruction framework built on rectified flow that incorporates auxiliary MRI modalities at inference time without retraining the ge

Why this matters
Why now

The continuous advancements in AI, particularly in generative models and rectified flow, are enabling more sophisticated solutions for complex problems like medical imaging reconstruction.

Why it’s important

This development significantly enhances the reliability and interpretability of AI-driven medical diagnostics, potentially leading to faster and more accurate disease detection and treatment planning.

What changes

MRI reconstruction can now leverage multi-modal data more effectively without retraining, reducing hallucination risks and improving diagnostic precision in clinical settings.
