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

Figure 3

Bland-Altman plots with limits of agreement (1.96 standard deviations) demonstrate the intraobserver, interobserver, and interstudy reproducibilities (S1 and S2) of CMR-FT for LV and RV strain assessments. The relative variability is defined as the difference between observations divided by their mean. LLSLAX: left ventricular long-axis longitudinal strain; LCSSAX: left ventricular short-axis circumferential strain; LRSSAX: left ventricular short-axis radial strain; RLSLAX: right ventricular long-axis longitudinal strain; RCSSAX: right ventricular short-axis circumferential strain.
