Magnetic Resonance in Medicine, Volume 95, Issue 1, Page 86-100, January 2026.Abstract Purpose Isotropic submillimeter high‐resolution functional MRI (fMRI) facilitates noninvasive investigation of neuronal activities at the mesoscale level, including cortical columns and laminae. However, the task‐evoked functional activity becomes less detectable when using single‐shot echo planar imaging (EPI) with parallel imaging techniques

Predictive signal modeling and multi‐rate filtering in accelerated cardiac MRI
Magnetic Resonance in Medicine, Volume 95, Issue 1, Page 585-600, January 2026.Abstract Purpose True real‐time cardiac MRI (CMR), necessary for capturing live cardiac dynamics and imaging irregular cardiac rhythms, remains challenging. In this article, we move toward real‐time CMR in multiple reconstruction frameworks via strategies to predict cardiac motion, improve computational efficiency, reduce artifacts, and preserve ...

Journal of Sensors, Volume 2026, Issue 1, 2026.Optical sensors play a significant role in clinical diagnostics, environmental monitoring, and personal healthcare; however, optical sensors generally suffer from the complexity of data, nonspecific responses, and computational issues in real‐time. In this review, we emphasize the integration of machine learning (ML) as a solution to these limitations ...
