This study introduces Federated Adversarial MRI Enhancement (FAME), a novel framework combining Federated Learning (FL) with Generative Adversarial Networks (GANs) to enhance MRI reconstruction while maintaining patient privacy. FAME utilizes a hybrid model aggregation strategy that dynamically weights updates from local generators, ensuring a balanced contribution based on dataset size and quality. Each local generator is trained on-site-specific data, while a global discriminator evaluates and refines the aggregated updates to improve image quality. FAME addresses key issues in medical imaging, including data privacy, model generalization, and robustness, by integrating advanced GAN architectures such as multi-scale convolutions, attention mechanisms, and Graph Neural Networks (GNNs). Differential privacy and secure aggregation protocols are implemented to protect sensitive data during training. Extensive experiments using the fastMRI Brain and Knee datasets, along with the BraTS 2020 and IXI dataset, show that FAME outperforms existing models, achieving superior PSNR and SSIM values.

A recent clinical study using EPR oximetry with OxyChip from our laboratory demonstrated the feasibility of tumor oxygen measurements in cancer patients (Schaner, et al. Front. Oncol. 2021). During this study, the need to improve oxygen measurement capability in tumors at depths greater than 10 mm became apparent. This prompted us to develop new designs of resonators (RF coils) with enhanced sensitivity for measuring deep-tissue oxygen levels. In this manuscript, we report the development of a new cylindrical surface dielectric resonator (c-SDR) designed with a ceramic dielectric material for substantially enhanced sensitivity and capability for deep-tissue oximetry. The c-SDR was constructed with a cylindrical dielectric material (ϕ 27.2 × 22.2 mm; ε = 160), 6-segmented coupling loop and copper shield to provide an active surface (aperture) of 25 mm with an operating frequency of 1.16 GHz (L-band) and an unloaded Q 600. The resonator could detect OxyChip (ϕ 0.6 × 5 mm) at a surface-to-sample depth of 50 mm in water or 30 mm in a tissue-emulating phantom with a signal-to-noise ratio of 5. Further evaluations of the c-SDR using OxyChip demonstrated its capability for oxygen measurements at depths of 27 mm for 1% oxygen and 15 mm for 5% oxygen in a tissue phantom.

This common conviction may not be correct in many microporous materials. Each pore size may be associated with more than one peak in the NMR relaxation time distributions: a single dominant peak and also possibly one or a few minor peaks. The appearance of minor peaks is due to the non-vanishing nonground eigenvalues of the diffusion–relaxation equation. Brownstein and Tarr (Phys Rev A 19:2446, 1979) described these features, but their solutions at conditions beyond the fast-diffusion regime are not widely adopted. We provide the derivation of Brownstein–Tarr equations for multi-exponential magnetic resonance relaxation decay for liquids in simple pore geometries. General solutions are presented for planar, cylindrical, and spherical pores—as well as two limiting cases of fast and slow diffusion for each geometry. Similar solutions are also relevant to first-order dilute reactions in porous media in heterogeneous reaction–diffusion systems.
