Synopsis

It has been shown that the BOLD delay calculated from resting-state fMRI can reveal perfusion information. In this study, the correlation between BOLD delay and CBF measured from ASL were explored. The results showed the inter-subject correlation between BOLD delay and CBF values. Meanwhile, the inter-group differences of the correlation coefficients between Moyamoya patients and healthy controls were also compared.
