Journal ArticleDOI
13C MRS studies of neuroenergetics and neurotransmitter cycling in humans.
TL;DR: The current state of 13 C MRS as it is applied to the study of neuroenergetics and neurotransmitter cycling in humans is reviewed, predominantly on recent findings in humans regarding metabolic pathways, applications to clinical research and the technical status of the method.
Journal ArticleDOI
Altered brain mitochondrial metabolism in healthy aging as assessed by in vivo magnetic resonance spectroscopy
Fawzi Boumezbeur,Fawzi Boumezbeur,Graeme F. Mason,Robin A. de Graaf,Kevin L. Behar,Gary W. Cline,Gerald I. Shulman,Gerald I. Shulman,Douglas L. Rothman,Kitt Falk Petersen +9 more
TL;DR: It is shown that healthy aging is associated with reduced neuronal mitochondrial metabolism and altered glial mitochondrial metabolism, which may in part be responsible for declines in brain function.
Journal ArticleDOI
Diffusion NMR spectroscopy.
TL;DR: DW‐MRS has been used to estimate the dimensions of the cellular elements that restrict intracellular metabolite diffusion in muscle and nerve tissue and can provide novel information on the cellular response to pathophysiological changes in relation to a range of disorders.
Journal ArticleDOI
Deuterium metabolic imaging (DMI) for MRI-based 3D mapping of metabolism in vivo
Henk M. De Feyter,Kevin L. Behar,Zachary Corbin,Robert K. Fulbright,Peter B. Brown,Scott McIntyre,Terence W. Nixon,Douglas L. Rothman,Robin A. de Graaf +8 more
TL;DR: Deuterium metabolic imaging is a novel, noninvasive approach that combines deuterium magnetic resonance spectroscopic imaging with oral intake or intravenous infusion of nonradioactive 2H-labeled substrates to generate three-dimensional metabolic maps that reveal glucose metabolism beyond mere uptake.
