In this work, we compared perfusion maps obtained with resting-state BOLD fMRI (no contrast agent used) to perfusion maps obtained with Dynamic Susceptibility Contrast (Gadolinium contrast agent) in 20 patients with cerebrovascular diseases. We also derived connectivity maps from the same data and analyzed the influence of time delays on the results.
