Age‐Related Low Frequency Amplitude Differences in Resting‐State Blood Oxygenation Level‐Dependent Signal in the Cerebellum

open access: yesHuman Brain Mapping, Volume 47, Issue 7, May 2026.
This study found that fractional amplitude of low frequency fluctuations in cerebellar Crus I/II is significantly greater in older adults as compared to younger adults. The higher amplitude in this region is associated with increased connectivity to cortical regions, and may be characteristic of healthy aging.

ꟻLIP‐Based Perceptual Optimization for Subpixel Rendering Filters

open access: yesJournal of the Society for Information Display, Volume 34, Issue 5, Page 361-367, May 2026.
We propose a two‐stage subpixel rendering framework combining MMSE‐based initialization and ꟻLIP‐guided perceptual optimization. The kernel is refined by minimizing the mean ꟻLIP error using a Nelder‐Mead optimizer to reduce perceptual distortion beyond RGB‐based methods.

Jointly Learned 3D Non‐Cartesian Sampling With Wave Encoding and Reconstruction for Neurovascular Phase Contrast MRI

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 5, Page 2554-2567, May 2026.
ABSTRACT Purpose To develop accelerated 3D phase contrast (PC) MRI using jointly learned wave encoding and reconstruction. Methods Pseudo‐fully sampled neurovascular 4D flow data (N = 40) and a simulation framework were used to learn phase encoding locations, wave readout parameters, and model‐based reconstruction network (MoDL) for a rapid 3D PC scan (

Accelerating Multiparametric Quantitative MRI Using Self‐Supervised Scan‐Specific Implicit Neural Representation With Model Reinforcement

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 5, Page 2963-2979, May 2026.
ABSTRACT Purpose To develop a self‐supervised scan‐specific deep learning framework for reconstructing accelerated multiparametric quantitative MRI (qMRI). Methods We propose REFINE‐MORE (REference‐Free Implicit NEural representation with MOdel REinforcement), combining an implicit neural representation (INR) architecture with a model reinforcement ...

High‐Resolution Diffusion‐Weighted Imaging With Self‐Gated Self‐Supervised Unrolled Reconstruction

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 5, Page 2852-2862, May 2026.
ABSTRACT Purpose High‐resolution diffusion‐weighted imaging (DWI) is clinically demanding. The purpose of this work is to develop an efficient self‐supervised algorithm unrolling technique for submillimeter‐resolution DWI. Methods We developed submillimeter DWI acquisition utilizing multi‐band multi‐shot EPI with diffusion shift encoding.
