A calibration‐based approach to real‐time in vivo monitoring of pyruvate C1 and C2 polarization using the JCC spectral asymmetry. (2nd April 2013) - Lau, Justin Y. C.
Abstract A calibration‐based technique for real‐time measurement of pyruvate polarization by partial integral analysis of the doublet from the neighbouring J‐coupled carbon is presented. In vitro calibration data relating the C2 and C1 asymmetries to the instantaneous C1 and C2 polarizations, respectively, were acquired in blood. The feasibility of using the in vitro calibration data to determine the instantaneous in vivo C1 and C2 polarizations was demonstrated in the analysis of rat kidney and pig heart spectral data. An approach for incorporating this technique into in vivo protocols is proposed. Copyright © 2013 John Wiley & Sons, Ltd.
