This work quantifies the accuracy of time-domain Voigt fitting of dissolved-phase 129Xe peak parameters (xenon in red blood cells and tissue/blood plasma). It is shown that time-domain Voigt fitting of dissolved-phase 129Xe resonances in the lungs is accurate to within 5% when the SNR values of the spectra are >100 and the gas phase resonance amplitude is < factor of 2 higher than each of the dissolved-phase 129Xe resonances.
