Free‐Breathing Hepatic Oxygen Extraction Fraction (OEF) Mapping Using Radial GESSE

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2840-2847, December 2026.
ABSTRACT Purpose Noninvasive assessment of hepatic oxygenation is relevant for evaluating liver both in acute and long‐term liver pathologies. However, existing methods are limited to single‐slice acquisitions and require breath‐holding. This study aims to develop and evaluate a motion‐robust technique for whole‐liver oxygen extraction fraction (OEF ...

Calibration‐Free Estimation of Cerebrovascular Reactivity From Resting‐State BOLD fMRI Using Reconstructed Respiratory Fluctuations

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2755-2766, December 2026.
ABSTRACT Purpose Cerebrovascular reactivity (CVR) provides an important index of vascular health and is conventionally quantified using a hypercapnic gas or breath‐hold challenge in conjunction with blood‐oxygen‐level‐dependent functional magnetic resonance imaging (BOLD‐fMRI).

Incomplete Spoiling Correction for 3D T1$$ {T}_1 $$ Mapping

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2848-2856, December 2026.
ABSTRACT Purpose Assess the impact of incomplete spoiling and spatial saturation on T1$$ {T}_1 $$ mapping using the variable flip angle (VFA) spoiled gradient recalled echo sequence (SPGR). Develop a correction for incomplete spoiling that results in an accurate estimate of T1$$ {T}_1 $$, essential for quantitative MRI applications.

Maternal Depression, Childhood Resting‐State Brain Connectivity, and Adolescent Depression During the COVID‐19 Outbreak

Developmental Psychobiology, Volume 68, Issue 6, November 2026.
ABSTRACT Adolescents of mothers with a history of depression are at increased risk for developing depression themselves. These adolescents may have been especially vulnerable to depression under conditions of stress, such as the beginning of the COVID‐19 pandemic.

Temporal Interference Modulates Medial Temporal and Frontoparietal Activity During Mnemonic Discrimination: A High‐Resolution Whole‐Brain fMRI Investigation

Hippocampus, Volume 36, Issue 6, November 2026.
ABSTRACT Mnemonic discrimination—the ability to distinguish between existing memories and similar new inputs—supports accurate memory in the face of interference (e.g., in a card game, recognizing that the card you are currently seeing, the King of Hearts, is distinct from the King of Diamonds you encountered earlier in the same hand).

Group‐Patch Joint Compression: Compressing Dynamic B0 and Static RF Spatial Modulations Across k‐Space Subregion Groups for Highly Accelerated MRI

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2106-2126, November 2026.
ABSTRACT Purpose To accelerate MRI further, rapid B0 field modulations can be applied during oversampled readout to capture additional physical information, as in Wave‐CAIPI/FRONSAC/local B0 coils modulation techniques. These methods, however, turn the Fourier readout into a non‐Fourier‐encoded dimension that cannot be reconstructed by FFT, posing ...
