Improving Multi-Center Generalizability of GAN-Based Fat Suppression using Federated Learning (2404.07374v1)

Published 10 Apr 2024 in eess.IV, cs.CV, and cs.LG

Abstract: Generative Adversarial Network (GAN)-based synthesis of fat suppressed (FS) MRIs from non-FS proton density sequences has the potential to accelerate acquisition of knee MRIs. However, GANs trained on single-site data have poor generalizability to external data. We show that federated learning can improve multi-center generalizability of GANs for synthesizing FS MRIs, while facilitating privacy-preserving multi-institutional collaborations.
