    Calculating 3D intramyocardial strain tensors in a single slice of myocardium using MRI
    (2006) Hess, Aaron; Meintjes, Ernesta
    Strain is a measure of cardiac deformation and provides information on the mechanical and functional properties of the heart. As this deformation occurs in three dimensions (3D), a 3D measure of strain is appropriate, however, currently the procedures for measuring 3D intramyocardial strain fields are limited to a handful of techniques. The only widely accepted method being the use of tagging in orthogonal image planes that requires the imaging of the entire myocardial volume, followed by lengthy and time consuming post processing. A method to combine cine displacement encoding with stimulated echoes (cine-DENSE) and cine strain encoded MRI (cine-SENC) for the formulation of the complete 3D strain tensor field for a single slice of myocardium is proposed.
