Fifty percent of the heart failure patients have diastolic dysfunction with preserved ejection fraction (HFpEF), and traditionally echocardiography is used for evaluating diastolic dysfunction due to its superior temporal resolution. We propose LV volume based metrics as a MR based index that is comparable to conventional echo based index for the evaluation of diastolic dysfunction. The results from this pilot study suggest that it is feasible to evaluate both systolic and diastolic function with a single set of high-temporal resolution cine SSFP images acquired during free breathing.
