the MR results. Velocity to noise ratio will improve with more accurate velocity encoding settings. More importantly, to be able to apply the PC-MRI scan in
patients, scan time needs to be shortened severely, for example by acceleration techniques.

For patients with a symptomatic internal carotid artery (ICA) stenosis, it is often difficult to identify the symptomatic artery for treatment due to the
variability in perfusion territories of the major cerebral arteries. For the basal ganglia, this imposes an even greater difficulty. Using selective arterial spinlabeling
MRI, this study found the nucleus caudatus in patients with a symptomatic ICA stenosis was more often fed by the contralateral ICA compared to
healthy control subjects (p=0.03). This was accompanied by reversed blood flow through the ipsilateral anterior part of the circle of Willis (p
