Applicability in paired IR and PSIR LGE images from patients in multi-center, multi-vendor studies: a Scatter plots (left column) and Bland-Altman plots (right column) of infarct size expressed as % of LVM for the EWA algorithm against infarct size by expert delineation in 49 patients from multi-center studies with paired magnitude inversion recovery (IR, top row) and phase sensitive inversion recovery LGE images (PSIR, bottom row). Left column: solid line = line of identity; dashed line = regression line. Right column: solid line = mean bias; dashed line = mean ± two standard deviations. b Typical segmentation by the EWA algorithm in one patient with paired IR (top row) and PSIR images (bottom row). The automatic EWA segmentation of the infarct is shown in yellow, the core of the infarct is shown in pink and microvascular obstruction is shown as the red line within the infarct. Endocardium is delineated in red and epicardium in green
