Quantitative analysis of cardiac left ventricular variables obtained by MRI at 3 T : a pre- and post-contrast comparison

, 2012
Short-axis cine images are acquired during cardiac MRI in order to determine variables of cardiac left ventricular (LV) function such as ejection fraction (EF), end-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV) and LV mass.
