Diffusion Tensor MRI and Spherical‐Deconvolution‐Based Tractography on an Ultra‐Low Field Portable MRI System

open access: yesHuman Brain Mapping, Volume 47, Issue 2, February 1, 2026.
A Portable ULF scanner (1a) imaged a subject (1b) and phantom (1c) to give T2 (2a) and DW (2b) acquisitions alongside a regularised phantom fieldmap (2c). These were processed to give corrected DTI (3a) and CSD (3b) derivatives and were used for whole‐brain tractography (3c) in a feasible acquisition duration.

Superconducting fault current limiters for grid protection

open access: yesTransformers Magazine, 2021
Superconducting fault current limiters are novel equipment for grid engineers. It presents unique features like ultra-fast current limitation, efficient reduction of fault current and very small footprint. It is eco-friendly and non-flammable. The article briefly discusses device basics, available options and recent practical advances in this field. As

The Sense of Smell (SoS) Atlas: Its Creation and First Application to Investigate COVID‐19 Related Anosmia With a Comprehensive Quantitative MRI Protocol

open access: yesJournal of Magnetic Resonance Imaging, Volume 63, Issue 2, Page 574-593, February 2026.
ABSTRACT Background The loss of smell (anosmia) has been noted in numerous diseases, including COVID‐19. Inflammatory and microstructural alterations are possible underlying mechanisms of anosmia in COVID‐19. However, no atlas exists to study olfaction and the associated tissue property changes.

MRI and Implant Safety at Low‐Field and Ultralow‐Field Strengths

open access: yesJournal of Magnetic Resonance Imaging, Volume 63, Issue 2, Page 364-377, February 2026.
ABSTRACT Despite its unequivocal value in radiological diagnosis, access to conventional high‐field MRI systems remains extremely uneven across the world. Access is particularly limited in underfunded and remote settings, due to the high cost and infrastructure requirements of MRI systems.

Radial TRASE: 2D RF encoding through mechanical rotation and active digital decoupling

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 2, Page 987-1001, February 2026.
Abstract Purpose Two‐dimensional (2D) transmit array spatial encoding (TRASE) previously required four radiofrequency fields; however, interactions between transmit (Tx) array elements caused significant challenges for 2D imaging. Here, we present a low‐cost, 2D radial encoding scheme (Radial TRASE) using a simplified two‐coil array.

Detection Limits of Blood Metabolites at Physiological Concentrations Using Benchtop 1$$ {}^1 $$H NMR

open access: yesNMR in Biomedicine, Volume 39, Issue 2, February 2026.
We demonstrate rapid, sensitive detection of key blood metabolites using an 80 MHz low‐field NMR spectrometer, benchmarking signal‐to‐noise ratios and acquisition efficiency across experimental designs. Millimolar metabolites such as glucose and lactate are reliably detected and quantified within seconds, while simulation‐assisted spectral fitting ...
