Table 2.

The normalized ASL signal, temporal SNR (tSNR) and cerebral blood flow (CBF) in gray matter (GM), averaged across subjects (mean ± standard deviation). Significant differences in tSNR between the labeling schemes were detected and labeled in Figure 7B. No significant difference in ASL signal or GM CBF was detected between the labeling schemes.
