Clinical experience of strain imaging using DENSE for detecting infarcted cardiac segments

Table 6 Interobserver and scan-rescan variability

	Inter observer		Scan-rescan
	ICC	95 % CI	ICC	95 % CI
Radial transmural strain SA	0.96	0.95–0.97	0.95	0.92–0.96
Radial transmural strain LA	0.93	0.91–0.95	-	-
Circumferential transmural strain	0.99	0.98–0.99	0.96	0.94–0.97
Longitudinal transmural strain	0.96	0.94–0.97	-	-

Inter-observer variability (two observers measuring on the same images) in 10 patients and scan-rescan results from one observer in 9 patients in the short axis direction. Intraclass Correlation Coefficient (ICC) is shown with 95 % Confidence Interval (CI)
