Magnetic Resonance Cine DENSE Dyssynchrony Parameters for the Evaluation of Heart Failure: Comparison to Myocardial Tissue Tagging

Objective We sought to assess the effectiveness of automated mechanical dyssynchrony (MD) parameters based on regional heterogeneity of strain (circumferential (CURE), longitudinal (LURE), and radial (RURE) uniformity ratio estimates) relative to parameters based on regional time to peak contraction using cardiac magnetic resonance (CMR) cine DENSE (Displacement Encoding with Stimulated Echoes) validated with myocardial tissue tagging (MTT) strain data.
