ns not significant (p value not reported), r Pearson correlation coefficient, RC reproducibility coefficient (% of mean), CV coefficient of variation
^aRepeatability data is given for single mid-ventricular slice, all other studies, data is for global myocardium, averaged from multiple slices. Where RC was not published, but sufficient data was provided, this has been calculated using 1.96*SD of difference. Similarly, all RC are given as % for ease of comparison
