In this work we assessed the intra- and inter-scan reproducibility of iVASO at multiple inversion times (TI) of blood in the cortex and the hippocampus. iVASO reproducibility was higher at shorter TIs for the hippocampus compared to the cortex. Reproducibility was assessed using intra-class correlation analysis and found to be similar to that of arterial spin labeling approaches.
