New Rician Likelihood Denoising Improves Cardiac MRI Quality

Researchers have developed a new self-supervised denoising method for cardiac MRI that addresses limitations of existing techniques. The proposed approach uses Rician likelihood estimation, which is better suited for MR magnitude images than the mean squared error loss used in Noise2Void-style methods. This new method produces unbiased denoised images and parametric maps, performing competitively with supervised denoising baselines. AI

IMPACT This research introduces a more accurate method for denoising cardiac MRI images, potentially leading to improved diagnostic capabilities and reduced scan times.

    Beyond MSE: Rician Likelihood Denoising for Self-Supervised Cardiac $T2$ and $T1\rho$ MRI

    arXiv:2609.31777v2 Announce Type: replace-cross Abstract: Magnetic resonance imaging involves an inherent trade-off among spatial resolution, acquisition time, and noise. This trade-off contributes to long scan times and high cost. Deep learning has improved image denoising, but …
