Comparison of spectra-related information from the iMQC and MAS spectra^*.

The left and right values are corresponding to the results of iMQC and MAS, respectively. The sensitivity is calculated as , where t2 = acquisition time, and SNR is the signal to noise ratio calculated by dividing the intensity of the creatine peak (3.05 ppm) by the standard deviation of noises in the region between 6.0 and 6.5 ppm. The linewidth at the half maximum of creatine peak (3.05 ppm) as a representative is measured.
