Does magnetic resonance feature tracking agree with tagging for measuring left ventricular myocardial deformation in healthy volunteers?
Magnetic resonance feature tracking shows reasonable agreement with tagging for circumferential global strain, but not longitudinal or radial strain, in healthy volunteers.
FT measurements of circumferential but not longitudinally or radially directed global strain showed reasonable agreement with tagging and acceptable inter-observer reproducibility. We record provisional ranges of FT deformation parameters at global, regional and segmental levels. They show evidence of variation with gender and myocardial region in the volunteers studied, but have yet to be compared with tagging measurements at the segmental level.
Augustine et al. (Tue,) studied this question.
