Figure 9.

RBC/TP ratio map from a short-TR90°,eff CSI acquisition (far left) compared to ratio maps based on XTC MRI measurements using six different discrete and CW saturation schemes with B1,rms values ranging from 1.7 to 31 μT with and without Δ-frequency correction for the RBC saturation, in a different rat than that shown in Fig. 8. The corrected RBC/TP ratio maps within the orange box are in good agreement with the CSI measurement. Lower B1,rms values result in insufficient depolarization and noisy maps, while higher-powered saturations suppress the RBC component, skewing the ratio downward.
