DSA remains the method that can best measure collateral
extents, but it is relatively time-consuming, invasive,
and costly. 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 suggest that multi-post
labeling delay time three dimensional pseudo-continuous
arterial spin labelling technique may be a useful tool
to investigate the collateral perfusion in patients with
intracranial arterial stenosis.
