Arterial spin labeled (ASL) perfusion fMRI offers the
possibility of measuring cerebral blood flow (CBF) and
assessing functional connectivity (FC) by means of
evaluating the temporal correlations in the fluctuations
of the CBF time series. The goal of this study was to
evaluate and compare the reproducibility of FC maps
derived from CBF and concurrent BOLD data. The results
of this test-retest study show that FC derived from CBF
data offers better reproducibility of the connectivity
values, although slightly lower reproducibility of the
spatial localization of the identified networks.
