The purpose of this study was to demonstrate the possibility of contrast-enhanced 3D cine balanced steady-state free precession (SSFP) imaging as cine viability cardiac MRI that exhibit the myocardial wall motion and viability in the same imaging sections simultaneously. Patients underwent 2D cine balanced SSFP, pre- and postcontrast 3D cine balanced SSFP, and delayed contrast-enhanced 2D MRI. Contrast-enhanced 3D cine balanced SSFP imaging provided high SNR and CNR of the damaged myocardium, as well as accurate estimations of the ejection fraction and myocardial mass. Contrast-enhanced 3D cine balanced SSFP imaging may be useful for cine viability images of the heart.
