The aim of this study was to investigate the diagnostic performance of contrast-enhanced compressed sensing (CS) whole-heart 3T MR angiography in the detection of clinical significant coronary artery stenosis by using CTA as a reference. The preliminary results indicate that the contrast-enhanced CS coronary MR angiography has a good consistency in evaluating coronary artery disease in comparison to CTA and a short enough acquisition time that can be applied in the waiting time between contrast injection and late gadolinium enhancement imaging.
