Linear regression and Bland-Altman analyses comparing myocardial late enhancement volume using MIR and PSIR for FWHM-based analysis. Late enhancement is reported as percent of total LV myocardial volume at 2, 3, and 5 SD from the mean signal intensity of normal reference myocardium. Left: Linear regression analysis. Values indicate the mean difference of MIR-based scar volume quantification relative to PSIR. Right: Bland-Altman analysis. Long dashed lines represent bias, dotted lines represent 95 % confidence intervals
