In this study, we aimed to investigate the feasibility of zero echo time magnetic resonance angiography (zTE-MRA) in the characterization of cerebrovascular diseases. Comparing with the time of flight (TOF) MRA, zTE-MRA showed more robust performance in depicting cerebrovascular diseases with dramatically reduced acoustic noise, higher signal homogeneity, less venous signal/artifact and higher inter-modality agreement and correlation with computed tomography angiography (CTA). We therefore demonstrated that zTE MRA could be a promising technique and further applied routinely in the clinic for patients with cerebrovascular diseases.
