Reproducibility of different LGE quantification methods. Intra-rater and inter-rater variability for each LGE quantification method (calculated as 1 - intraclass correlation coefficient [ICC]) of the different methods is lowest in visual scores and FWHM. Intra-rater variability is less marked than inter-rater variability, as would be expected. Of the quantifications methods significantly associated with MACE, FWHM, LGE-VPS and LGE-VTS showed the best inter- and intra-rater variability. FWHM = Full width half maximum, SD = Standard deviation; LGE-VPS = visual LGE presence score; LGE-VTS = visual LGE transmurality score; MACE = Major adverse cardiovascular event
