Clinical feasibility of using Compressed SENSE (CS-SENSE) technology to shorten the scan time of Time-of-flight (TOF) magnetic resonance angiography (MRA) and optimal acceleration factor were investigated via a multi-center study. Ninety subjects underwent 8 customized TOF-MRA sequences including sequences with CS-SENSE technology, SENSE technology and without acceleration technology. Subjective assessments including evaluations of artery branches and artifacts, and objective measurements including signal-to-noise ratio, contrast-to-noise ratio and peak signal-to-noise ratio were performed. The results indicated that TOF-MRA using CS-SENSE with an optimal acceleration factor (4 to 6) provided comparable results compared with traditional TOF-MRA sequences, and significantly increased the scan efficiency.
