Introduction The application of C (or other low γ nuclei) NMR spectroscopy and imaging for clinical diagnosis has been constrained by the extremely long imaging and spectroscopy acquisition times that are required to obtain high SNR under physiological conditions (low natural abundance of C, low concentration of C-compounds, physiological temperature etc.). However, this obstacle could be overc...
