The feasibility of non-contrast-enhanced coronary MR angiography (CMRA) with acceleration by compressed sensing (CS) was assessed in patients with suspected coronary artery diseases on a 3.0 T scanner, compared with conventional coronary MRA. Results indicate that the whole-heart non-contrast CMRA accelerated by CS with a factor of 4 obtained relatively high sensitivity, positive predictive value, negative predictive value and accuracy in a significantly shortened acquisition time compared with conventional CMRA.
