Selective proton-observed, carbon-edited (selPOCE) MRS method for measurement of glutamate and glutamine 13 C-labeling in the human frontal cortex - https://pubmed.ncbi.nlm.nih.gov/29134686/
Visual selective attention is the ability to modulate perception in order to optimize processing according to our current task goals (Carrasco, 2011). - https://www.frontiersin.org/articles/10.3389/fpsyg.2018.0110...
In frequency-selective MRI, frequency-tuned RF pulses are used to either excite or suppress water or fat proton signals prior to data acquisition, in a manner similar to magnetization preparation schemes [109-114]. - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4001818/
Proton-observed carbon-edited (POCE) NMR spectroscopy is commonly used to measure 13C labeling with higher sensitivity compared to direct 13C NMR spectroscopy, at the expense of spectral resolution. - https://pubmed.ncbi.nlm.nih.gov/16402370/#:~:text=Proton-obs...
