  1. The ICC was calculated for absolute agreement of the strain values. SD standard deviation; Diff Difference; ICC intraclass correlation coefficient; CoV coefficient of variation; ECV extracellular volume; ROI region of interest. Native: prior to Gadolinium contrast agent application, post: 15 min post application
