Flow related artifacts in continuous arterial spin labeling (cASL) zero-echo-time (ZTE) magnetic resonance angiography (MRA) could influence the visualization of vasculature. This study aimed to investigate the clinical feasibility of ZTE-MRA with hybrid arterial-spin-labeling (hASL) tagged for assessing the intracranial artery diseases assessment. Our clinical results indicated that relative to conventional ZTE-MRA, hASL-ZTE-MRA was more robust and superior in the depiction of intracranial artery diseases and follow-up assessment in a clinical population while maintaining a ZTE-derived nature.
