Does mitral annular velocity derived from cine MRI accurately correlate with tissue Doppler echocardiography in healthy volunteers?
Mitral annular velocity can be accurately extracted from high temporal resolution cine MR, showing substantial concordance with tissue Doppler echocardiography for evaluating diastolic function.
Effect estimate: Concordance correlation 0.64
Assessment of mitral annular tissue velocity plays an essential role in the evaluation of diastolic dysfunction. We have previously shown that mitral annular velocities can be derived from standard four-chamber cine SSFP images by automatically detecting and tracking the mitral valve insertion points 1. However, this method has not been validated against tissue Doppler echocardiography, the standard clinical method for evaluating diastolic function.
Guetter et al. (Wed,) conducted a observational in Healthy volunteers (n=9). Cine MRI (SSFP) derived mitral annular velocity vs. Tissue Doppler echocardiography was evaluated on Concordance correlation of early diastolic (e') mitral annular velocities (Concordance correlation 0.64). Mitral annular early diastolic velocity (e') derived from cine MRI showed substantial concordance (correlation 0.64) with tissue Doppler echocardiography in healthy volunteers.
