ECV midventricular SAX 0.31 (2.23) 0.91 (0.85–0.94) 8.3%
ECV septal ROI 0.24 (1.75) 0.95 (0.93–0.97) 6.6%
  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
