The relaxometry hype cycle

Frontiers 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.

Intracellular Relaxometry, Challenges, and Future Directions

ACS Central Science, 2022
Nitrogen vacancy (NV) centers change their optical properties on the basis of their magnetic surroundings. Since optical signals can be detected more sensitively than small magnetic signals, this technique allows unprecedented sensitivity.

Color‐map recommendation for MR relaxometry maps

Magnetic Resonance in Medicine
To harmonize the use of color for MR relaxometry maps and therefore recommend the use of specific color‐maps for representing T1$$ {\mathrm{T}}_1 $$ , T2$$ {\mathrm{T}}_2 $$ , and T2*$$ {\mathrm{T}}_2^{\ast } $$ maps and their inverses.

A Rapid and Sensitive Method for the Determination of Chitosan Concentration by NMR Relaxometry. [PDF]

Magn Reson Chem
ABSTRACT A rapid, reagent‐free method for the quantification of chitosan in aqueous solutions was developed using 1H nuclear magnetic resonance (NMR) relaxometry. Transverse relaxation times (T2) of chitosan solutions (5–1000 mg/L) were measured with a Carr–Purcell–Meiboom–Gill (CPMG) sequence on a benchtop NMR relaxometer.

How to Disentangle Cation and Anion Dynamics of Fully Protonated Ionic Liquids: A Fast Field Cycling NMR Case Study. [PDF]

Magn Reson Chem
This work presents the first FFC NMR relaxometry study of a fully protonated ionic liquid, [TEA][OMs]. Using selective partial deuteration, cation and anion dynamics were disentangled, enabling the hidden cation–anion relaxation contributions to be quantified and the total relaxation rate to be reconstructed.

Zero- to low-field relaxometry of chemical and biological fluids

Communications Chemistry, 2023
Nuclear magnetic resonance (NMR) relaxometry is an analytical method that provides information about molecular environments, even for NMR “silent” molecules (spin-0), by analyzing the properties of NMR signals versus the magnitude of the longitudinal ...

Variability and reproducibility of multi-echo T2 relaxometry: Insights from multi-site, multi-session and multi-subject MRI acquisitions

Frontiers in Radiology, 2022
Quantitative magnetic resonance imaging (qMRI) can increase the specificity and sensitivity of conventional weighted MRI to underlying pathology by comparing meaningful physical or chemical parameters, measured in physical units, with normative values ...

Combined diffusion‐relaxometry microstructure imaging: Current status and future prospects

Magnetic Resonance in Medicine, 2021
Microstructure imaging seeks to noninvasively measure and map microscopic tissue features by pairing mathematical modeling with tailored MRI protocols. This article reviews an emerging paradigm that has the potential to provide a more detailed assessment
