Quantification of Biventricular Myocardial Strain Using CMR Feature Tracking: Reproducibility in Small Animals

<div>Comparison of biventricular myocardial strain of CMR-FT between nexilin knockout heterozygous (Het) and wild-type (WT) mice. LLS<sub>LAX</sub>: left ventricular long-axis longitudinal strain; LCS<sub>SAX</sub>: left ventricular short-axis circumferential strain; LRS<sub>SAX</sub>: left ventricular short-axis radial strain; RLS<sub>LAX</sub>: right ventricular long-axis longitudinal strain; RCS<sub>SAX</sub>: right ventricular short-axis circumferential strain. <svg height="13.532pt" id="M82"
