Regularization by Neural Style Transfer for MRI Field-Transfer Reconstruction with Limited Data (2308.10968v2)

Abstract: Recent advances in MRI reconstruction have achieved remarkable success with deep learning-based models. However, most methods depend on large-scale, task-specific datasets, leaving reconstruction in data-limited settings as a critical but underexplored challenge. Regularization by denoising (RED) is a general pipeline that incorporates a denoiser as a prior for image reconstruction, showing promising results in various image processing tasks, including denoising, deblurring, and super-resolution. In this work, we propose a regularization by neural style transfer (RNST) method to further leverage the priors from the neural transfer and denoising engine. RNST effectively reconstructs high-quality images from noisy, low-quality inputs across varying image styles, even with limited data. We validate RNST on clinical MRI scans, demonstrating its ability to significantly improve image quality. These findings underline the potential of RNST for MRI field-transfer reconstruction and its promise in addressing reconstruction tasks in data-constrained scenarios.
