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.
