Sodium is an essential ion that plays a central role in many physiological processes
including the transmembrane electrochemical gradient and the maintenance of the body's …

Sodium magnetic resonance imaging (23Na‐MRI) is a highly promising imaging modality
that offers the possibility to noninvasively quantify sodium content in the tissue, one of the …

With the increasing availability of ultra-high field MRI systems, studying non-proton nuclei (X-
nuclei), such as 23 Na and 31 P has received great interest. X-nuclei are able to provide …

The goal of this study was to evaluate the reproducibility and repeatability of tissue sodium
concentration (TSC) measurements using 23Na MRI in skeletal muscle tissue. 23Na MRI …

Objectives The aims were to investigate if potassium (39 K) magnetic resonance imaging
(MRI) can be used to analyze changes in the apparent tissue potassium concentration …

Purpose To validate the feasibility of quantitative combined potassium (39K) and sodium
(23Na) MRI in human calf muscle tissue, as well as to evaluate the reproducibility of the …

Noninvasively assessing tissue potassium concentrations (TPCs) using potassium magnetic
resonance imaging (39K MRI) could give valuable information on physiological processes …

Purpose To compare three anisotropic acquisition schemes and three compressed sensing
(CS) approaches for accelerated tissue sodium concentration (TSC) quantification using 23 …

Purpose To implement an accelerated MR‐acquisition method allowing to map relaxation
and absolute concentration of sodium within skeletal muscles at 3T. Methods A fast‐UTE‐2D …

ABSTRACT Combined 23Na/39K MRI at 7 T can highlight ion disturbances in skeletal
muscle tissue. In this work, we investigated if the apparent tissue potassium concentration …
