The relaxometry hype cycle

open access: yesFrontiers in Physiology, 2023
Relaxometry is a field with a glorious and controversial history, and no review will ever do it justice. It is full of egos and inventions, patents and lawsuits, high expectations and deep disillusionments.

Intervertebral Disc Elastography to Relate Shear Modulus and Relaxometry in Compression and Bending [PDF]

open access: yesBioengineering
Intervertebral disc degeneration is the most recognized cause of low back pain, characterized by the decline in tissue structure and mechanics. Image-based mechanical parameters (e.g., strain, stiffness) may provide an ideal assessment of disc function ...

Voxel-based relaxometry: a new approach for analysis of T2 relaxometry changes in epilepsy

open access: yesNeuroImage, 2004
The measurement of the T2 relaxation time (T2 relaxometry) had been established as a reliable tool for the assessment of certain conditions such as temporal lobe epilepsy. The standard procedure for analysis of T2 data uses manually drawn regions of interest (ROIs).

Asphalt-Binder Mixtures Evaluated by T1 NMR Relaxometry

open access: yesPhyschem
Asphalt pavements make up a majority of the essential transportation systems in the US. Asphalt mixtures age and degrade over time, reducing the pavement performance. Pavement performance critically depends on the aging of asphalt binder.

Normative T<sub>1</sub> and T<sub>2</sub> Brain Atlases Across the Adult Lifespan in a Chinese Cohort: Multicenter Quantitative MRI Benchmarks for Ageing and Neurodegenerative Research. [PDF]

open access: yesHum Brain Mapp
Normative voxel‐wise T1 and T2 brain atlases were constructed from 947 healthy adults across 11 imaging centers. The atlases model age‐ and sex‐related trajectories with high intersite reproducibility, providing quantitative reference maps for individual‐level interpretation and harmonized studies of brain aging and neurodegeneration.

Development of Positively Charged Poly-L-Lysine Magnetic Nanoparticles as Potential MRI Contrast Agent

open access: yesNanomaterials, 2023
A colloidal solution of magnetic nanoparticles (MNPs) modified with biocompatible positively charged poly-L-lysine (PLL) with an oleate (OL) layer employed as an initial coating was produced as a potential MRI contrast agent.

Nuclear Magnetic Resonance with Fast Field-Cycling Setup: A Valid Tool for Soil Quality Investigation

open access: yesAgronomy, 2020
Nuclear magnetic resonance (NMR) techniques are largely employed in several fields. As an example, NMR spectroscopy is used to provide structural and conformational information on pure systems, while affording quantitative evaluation on the number of ...
