Diastolic dysfunction is commonly assessed by echocardiography, but not by cardiovascular magnetic resonance (CMR). To evaluate diastolic function, the mitral annular flow (E) and velocity (e’) at the early rapid filling phase are measured. While E can be accurately measured by CMR, methods for measuring e' need to be established. In this study a feature tracking based method for measuring e' is applied to CMR images, and validated against echocardiography. There was an agreement between the methods, but sources of disparities between CMR and echocardiographic e’ measurements need to be further studied in order to improve the accuracy of e’ measurement by CMR.
