  1. Strain measurements are continuous variables represented by median and interquartile range. Wilcoxon signed rank test was used to calculate the p value for manual values and their respective automated values. Automated GCS and GRS all slices were compared to the manual method of obtaining the average of 3 slices. GCS, global circumferential strain; GLS, global longitudinal strain; GRS, global radial strain.
