Re-test reliability of the tagged CSF outflow measurements for two participants. Percent differences in PH and TTP have less than 10%. For participant 1, there was little difference in outflow metrics between the two scans. For participant 2, there was no difference in PH between scans, and little difference in TTP, but the larger difference in MTT (41%) between the two scans resulted in somewhat more variability between scans for rCFV and rCFF (23%).
