A Non-enhanced Hybrid Arterial Spin Labeling MRA (NoHASL
MRA) technique for assessment of the extracranial
cervical arteries was evaluated. 15 patients with
suspected cerebral ischemia underwent NoHASL followed by
contrast enhanced MRA (CE-MRA). 18 arterial segments
were assessed by 2 neuroradiologists for diagnostic
confidence, internal carotid artery and vertebral artery
stenosis against CE-MRA as the reference standard. There
was no significant difference between dichotomized
diagnostic and non-diagnostic confidence scores for the
ICA, with moderate correlation between ICA bulb absolute
diameters. NoHASL shows promise as a relatively rapid,
non contrast sequence for assessment of cervical
arterial disease.
