Comparison of histological staining regional analysis 1 SD and 2 SD thresholds for ASL perfusion mapping. (A) Quantification of IS/LV% from TTC histological staining using ImageJ planimetry where red signal represents infarcted tissue (i). ASL perfusion mapping analyzed with 2 SD threshold for IS/LV% with red signal representing putative infarct region (ii). Histology and MR images have different slice thicknesses and cardiac contraction states and therefore should not be compared slice-by-slice. (B) Quantification of AAR/LV% from histological staining using ImageJ planimetry where grey signal representing putative AAR region and red signal indicating normal Evans blue perfusion (i). ASL perfusion mapping analyzed with 1 SD threshold for AAR/LV% with grey signal representing putative AAR region and red signal indicating normal perfusion (ii).
