Evaluation of Left Ventricular Diastolic Function with Cardiac MR Imaging

Abstract: Assessment of left ventricular (LV) function with cardiac magnetic resonance (MR) imaging is often limited to evaluation of systolic function, including analysis of regional wall motion, measurement of mass and volume, and estimation of ejection fraction. However, diastolic dysfunction is present in various heart diseases, particularly in heart failure with preserved ejection fraction, which is increasingly prevalent and is associated with a poor prognosis. In daily practice, the assessment of diastolic functi… Show more

“…Typical imaging parameters of VENC-MRI were as follows: slice thickness 6 mm, repetition time 35.6 ms, echo time 2.33 ms, number of segments 3, acquired temporal resolution 24-56 ms, 20°flip angle, 25 calculated phases and pixel spacing 4.5×3.1 mm. Encoding velocity was set to 130 cm/s [12].…”

“…The criteria for diastolic dysfunction from the analysis of the TMF curve were established according to published data [12]. Normal diastolic function was defined as an E/A between 1 and 2 and MDT between 150 and 220 ms.…”

“…This method requires segmentation of the LV and delineation of the endocardium in all cardiac cycle phases, which is time-consuming in terms of post-processing (Fig. 2); thus, it is rarely used (6,7).…”

“…Assessment of mitral inflow and pulmonary vein flow by CMRI phase-contrast imaging is based on similar parameters to those obtained by Doppler echocardiography and reflects the LV filling pattern (7)(8)(9). Pressure gradients can also be calculated using the modified Bernoulli equation: Pressure gradient (mmHg)=4V max 2 (m/s), where V max is the peak velocity (10).…”
