This leads to an improvement in image reconstruction fidelity over generative models that rely only on a marginal prior over the image contrast of interest.

Magnetic Resonance Imaging (MRI) is a widely used medical imaging modality boasting great soft tissue contrast without ionizing radiation, but unfortunately suffers from long acquisition times.
