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.

Offline Reconstruction of Diffusion MRI Acquisitions for Comparison Between Complex PCA‐Based and AI‐Based Denoising

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 435-447, July 2026.
ABSTRACT Purpose Optimal diffusion MRI (dMRI) data for image denoising is often unavailable from scanner reconstruction. In this work, we make available an offline reconstruction pipeline for GE dMRI acquisitions, giving access to complex dMRI data. Furthermore, we compare the efficacy of GE HealthCare's AIR‐Recon DL (ARDL), a proprietary convolutional

Creation of an MRI‐Based Three‐Dimensional Common Wombat (Vombatus ursinus) Brain Atlas and Linking Brain Morphometry to Wombat Behaviour

Anatomia, Histologia, Embryologia, Volume 55, Issue 4, July 2026.
ABSTRACT Marsupials lack a corpus callosum; in its place Diprodontia have a fasciculus aberrans connecting the hemispheres. However, despite this uniqueness, the realm of marsupial brain anatomy remains largely unexplored, especially through the lens of modern imaging techniques.

Corticospinal Subfiber Neurite Density Index Detects Upper Motor Neuron Degeneration in Prediagnostic Patients With Sporadic Amyotrophic Lateral Sclerosis

European Journal of Neurology, Volume 33, Issue 7, July 2026.
CST subfiber NDI values were reduced in prediagnostic ALS patients before clinically evident typical upper motor neuron signs emerged. Combining serum NfL with CST subfiber NODDI metrics showed higher diagnostic performance than single markers for differentiating prediagnostic ALS from healthy and ALS‐mimic controls.

Architecture of lower leg muscles in children: Reference curves and potential mechanisms of growth

Journal of Anatomy, Volume 249, Issue 1, Page 54-67, July 2026.
Muscle architecture (physiological cross‐sectional area, fascicle lengths and pennation angle) was measured from multimodal MRI scans of the lower legs of 197 children aged ≤15 years. We showed that lower leg muscle volumes (product of PCSA and fascicle length) increase primarily through increases in PCSA (transverse growth) rather than increases in ...

Elucidation of Architectural and Compositional Factors Associated With Inter‐Individual Variability in Passive Shear Modulus of the Human Vastus Lateralis in Young Healthy Males

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 7, July 2026.
ABSTRACT Human skeletal muscle exhibits substantial inter‐individual heterogeneity in passive mechanical properties; however, the mechanistic basis underlying this variability remains poorly understood. We aimed to comprehensively examine how compositional and architectural factors are associated with individual variability in passive shear modulus of ...
