A Numerical Alternative to MR Thermometry for Safety Validation of Multi‐Channel RF Transmit Coils

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 469-484, July 2026.
ABSTRACT Purpose This study proposes a numerical technique to estimate peak local specific absorption rate (SAR) uncertainty of multi‐channel RF coils during the process of safety validation as an alternative to experimental temperature and electric‐field measurements, and demonstrates its use to enable human studies at 10.5 T.

Double Asymmetric Spin Echo EPI (dASE‐EPI) Enables fMRI of the Entire Rat Brain at 9.4 T

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 366-373, July 2026.
ABSTRACT Purpose Development and evaluation of a double asymmetric spin echo planar imaging (dASE‐EPI) sequence to balance sensitivity to blood oxygenation level‐dependent (BOLD) contrast with mitigation of susceptibility‐induced intravoxel spin dephasing in ultra high‐field rodent brain imaging.

MRI Goes Mobile: Assessing the Reliability and Repeatability of a Mobile vs. Stationary 1.5 T MRI for Functional Neuroscience Studies

NMR in Biomedicine, Volume 39, Issue 7, July 2026.
We present a technical feasibility study validating two mobile 1.5 T MRI scanners against a stationary system using a five‐subject test‐retest protocol (N = 50 datasets). Following relocation, hardware performance remained stable, with no systematic bias in B0 homogeneity or B1+ maps.

Dynamic Network Reconfiguration of Brain Function During Exposure to Aversive Stimuli

Obesity, Volume 34, Issue 7, Page 1446-1456, July 2026.
ABSTRACT Objective Obesity, a critical public health challenge, involves dysregulated food stimuli responses central to its pathophysiology. Aversion to harmful food is protective, but dynamic brain network reorganization during aversion processing in obesity and its clinical implications remain inadequately understood.

The Interplay Between Sleep Disturbance, Glymphatic Dysfunction and Altered Brain Networks in Internet Gaming Disorder: A Multimodal Neuroimaging Study

Addiction Biology, Volume 31, Issue 7, July 2026.
This multimodal neuroimaging study explores the neurobiological mechanisms of Internet Gaming Disorder (IGD) by integrating DTI–ALPS and resting–state functional connectivity. The findings reveal that individuals with IGD exhibit reduced glymphatic system–related function, which is significantly associated with poorer subjective sleep quality ...

The Effect of Dopaminergic Medication on Impulse Control and Compulsive Behaviour: A Translational Perspective

Basic &Clinical Pharmacology &Toxicology, Volume 139, Issue 1, July 2026.
ABSTRACT Dopaminergic medication used in disorders like Parkinson's disease (PD) and restless legs syndrome can cause impulsive‐compulsive behaviour (ICB), often with strong negative effects on patients' quality of life. This narrative review presents translational evidence on iatrogenic ICB, taking findings from epidemiological, clinical, neuroimaging

Multiband functional magnetic resonance imaging (fMRI) for functional connectivity assessments

, 2018
During resting state the brain exhibits synchronized activity within all major brain networks. Using blood oxygen level dependent (BOLD) resting state functional magnetic resonance imaging (fMRI) based detection it is possible to quantify the degree of correlation, connectivity, between regions of interest and assess information regarding the integrity

Psilocybin as a novel treatment for chronic pain

British Journal of Pharmacology, Volume 183, Issue 14, Page 3992-4005, July 2026.
Abstract Psychedelic drugs are under active consideration for clinical use and have generated significant interest for their potential as anti‐nociceptive treatments for chronic pain, and for addressing conditions like depression, frequently co‐morbid with pain.
