Traditional 3D-TOF Magnetic Resonance Angiography (MRA) in carotid imaging needs a relatively long scan time and is prone to be disturbed by motion artifacts such as vascular pulsation, respiratory movement, and some other physiological factors. A combination of compressed sensing (CS) can achieve high acceleration factors and thus lead to a significant reduction of scan time. Here, we investigated the impact of acceleration factors of compressed sensing on the image quality of 3D-TOF-MRA for cervical vessels. CS acceleration factor of 6 is recommended for clinical 3D-TOF carotid MRA to achieve an optimal balance between imaging time and image quality.
