Quantitative myocardial T1 mapping provides in-vivo tissue characterization for assessment of cardiomyo-pathies. Pre and post-contrast T1 maps can be used to calculate the extracellular volume fraction (ECV) to detect diffuse myocardial fibrosis. Several imaging approaches have recently been proposed for measuring T1 values [1-4], but no head-to-head comparison has been reported to cross-examine their accuracy and reproducibility. In this study, we compared both T1 maps and ECV measurements from the following tech
