A novel algorithm is presented for tracking blood flow through the whole brain neurovasculature using 4D flow imaging data. The method incorporates probabilistic streamlines, displacement corrections, and additional fluid constraints. The algorithm was tested in 5 patients with aneurysms or arteriovenous malformations (AVMs). Good agreement is seen when compared to pseudo-continuous arterial spin labeling (PCASL). The technique also allows for retrospective seed placement to selectively measure downstream vessels, or evaluate AVM feeding and draining.
