DSA remains the method that can best evaluate collateral
extents, but it is relatively time-consuming, invasive,
costly, and cannot provide quantitative measurement.
Determining the presence and adequacy of collateral
blood flow is important in patients with severe
intracranial stenosis or occlusion due to collateral
flow can maintain cerebral circulation and may be
another potential therapeutic target in acute ischemic
stroke. Our study suggests that multi-post labeling
delay time 3D pCASL technique may be a useful tool to
quantitative the collateral perfusion in patients with
intracranial arterial stenosis.
