Diagnosis of Coronary artery disease using MRI remains a challenge due to the long scan times, limited spatial resolution, and low signal-to-noise of MRI technique. Compressed Sensing (CS) is a novel technique to accelerate the imaging and improve detection of coronary stenosis by coronary MRI. Results of this study indicate that there was no statistical difference in coronary artery image quality from the scanning with CS acceleration factors (AF) of 2, 4, 6. Since CS AF of 6 provides the shortest scan time and favorable image quality, this might be an optimal setting for clinical whole-heart coronary MRI.
