The purpose of this study was to optimize and evaluate a
3D radial balanced steady-state free precession arterial
spin labeled imaging sequence for high-contrast, rapid
nonenhanced MR angiography of the extracranial carotid
arteries. Through the use of higher radial
undersampling, the the feasibility of rapid carotid MR
angiography with the technique was also evaluated.
