While many studies assessed the reproducibility of ASL,
very few studies investigated pCASL reproducibility.
More importantly, pCASL reproducibility has not been
reported in specific sub-cortical brain regions such as
the thalamus and the cerebellum. These
regions-of-interest are of particular interest for
applications in diabetes9 and neurodegenerative
diseases. Here we obtained test-retest data on healthy
human subjects to evaluate data variability within and
across sessions using a whole-brain pCASL protocol at
3T.
