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.
