A non-contrast 4-D MRA using stack-of-star golden angle acquisition (Radial-TrueSTAR) has been recently introduced, which can accelerate the imaging speed up to 3 fold, compared to conventional Cartesian acquisition. Here we evaluated the clinical utility of Cartesian- and Radial-TrueSTAR in cerebral arteriovenous malformation patients by comparison with time-of-flight and DSA. Our preliminary data demonstrates that Radial-TrueSTAR provides shorter scan time while preserving similar image qualities compared to Cartesian-TrueSTAR. Compared to TOF, the heterogeneity within the nidus can be observed using both Cartesian- and Radial-TrueSTAR. Radial-TrueSTAR may become a promising approach with reduced scan time and patient comfort in clinical applications.
