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.
