Use of contrast agents in whole heart coronary MRI is known to increase SNR and CNR. However, to take full advantage of the presence of contrast media, the scan times need to be shortened. In this work, we investigated a prospectively accelerated whole heart contrast-enhanced coronary MRI after a bolus infusion of Gd-BOPTA using low-dimensional-structure self-learning and thresholding (LOST), an improved CS reconstruction.
