recommendations! Published in 2022 at "Journal of Magnetic Resonance Imaging"

DOI: 10.1002/jmri.28321

Abstract: Testing MRI gradient‐induced heating of implanted medical devices is required by regulatory organizations and others. A gradient heating test of the ISO 10974 Technical Specification (TS) for active implants was adopted for this study of… read more here.

DOI: 10.1109/tim.2022.3154819

Abstract: Accurate measurement of carbon isotope abundance is extremely important for geochemical applications. In the seismic zone, measurement error caused by variable gas temperature must be compensated. In this study, a 13CO2 carbon isotope abundance sensor… read more here.

DOI: 10.1371/journal.pone.0281332

Abstract: Diffusion MRI classically uses gradient fields that vary linearly in space to encode the diffusion of water molecules in the signal magnitude by tempering its intensity. In spin ensembles, a presumably equal number of particles… read more here.
