The “question-mark” MR anatomy of the cervico-thoracic ganglia complex: can it help to avoid mistaking it for a malignant lesion on 68Ga-PSMA-11 PET/MR?

Radiology and Oncology, 2019
Detectable uptake of 68Ga-PSMA-ligands in sympathetic ganglia may potentially lead to mistaking them for malignant lesions. Our aim was to investigate the anatomy of cervico-thoracic-ganglia-complex (CTG-C) in the MR part of multimodal 68Ga-PSMA-11 PET ...

Overlap‐Kernel EPI: Estimating MRI Shot‐to‐Shot Phase Variations by Shifted‐Kernel Extraction From Overlap Regions at Arbitrary k‐Space Locations

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2131-2152, April 2026.
ABSTRACT Purpose In multi‐shot EPI, shot‐dependent phase fluctuations can introduce ghost artifacts, undermining advantages for enhancing resolution or reducing distortion, particularly in diffusion scans. Here, a novel self‐navigation strategy based on shift‐invariant kernel extraction is proposed, enabling robust estimation of phase inconsistencies ...

A unipolar head gradient for high‐field MRI without encoding ambiguity

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 1266-1278, February 2026.
Abstract Purpose MRI gradients with a conventional, bipolar design generally face a trade‐off among performance, encoding ambiguity, and radiofrequency selectivity used to circumvent said ambiguity. This problem is particularly limiting in cutting‐edge brain imaging performed at field strengths ≥ 7 T and using high‐performance head gradients.

Non‐monotonic time‐ and frequency‐dependent diffusion kurtosis in the human brain revealed by pulsed and oscillating gradient experiments

Magnetic Resonance in Medicine, Volume 94, Issue 6, Page 2358-2373, December 2025.
Abstract Purpose To investigate the time and frequency dependence of diffusion kurtosis in the in vivo human brain with pulsed (PGSE) and oscillating gradient spin‐echo (OGSE) experiments over a range of diffusion times and frequencies using high‐performance gradients.

Enhanced spectral response in frequency‐dependent diffusion measurements using a linear encoding model

Magnetic Resonance in Medicine, Volume 94, Issue 6, Page 2405-2420, December 2025.
Abstract Purpose To devise a more comprehensive quantitative representation for spectral encodings in frequency‐dependent diffusion measurements for improved estimation of D(ω). Theory and Methods Whereas a spectral diffusion measurement is typically represented by a Dirac delta function at a single attributed frequency, spectral response is ...

Water Relations and Physiological Traits Associated with the Yield Components of Winter Wheat (Triticum aestivum L.)

Agriculture
Water stress in agricultural systems may occur slowly or abruptly. Plant reactions to stress differ with regard to its level and duration. The level of plant susceptibility to water deprivation primarily depends on the management of the water content and

From Stress to Recovery: Divergent Chilling Responses in Contrasting Miscanthus sinensis Genotypes

GCB Bioenergy, Volume 17, Issue 12, December 2025.
Chilling temperatures severely constrain early‐season establishment of C4 bioenergy crops. Using time‐resolved physiological, hormonal, transcriptomic, and cell wall analyses of two Miscanthus sinensis genotypes contrasting in chilling tolerance, we show that resilience arises from sustained, coordinated stress and recovery responses rather than rapid ...

Can endurance athletes benefit from vegetarian diets?

Quality in Sport
The performance of an athlete is the result of a complex interplay of various factors, with diet representing a particularly crucial component. Nutritional profiles of vegetarian diets vary considerably from those of omnivorous diets.
