(A–E). Selection of typical histology cross-sections of carotid plaques seen when moving from proximal to distal along the length of the carotid plaque. Cross-sections (A–C) are seen proximal to the flow divider and (D,E) distal to the flow divider. Row 1: Miller’s elastic stain. Row 2: segmentation of the necrotic core (NC), fibrin, and artifact, based on the combination of histochemical staining procedures performed. Row 3: CD68+ immunohistochemical stain. CD68-positive areas are marked in red. Row 4: segmentation of CD68+ stained slides, showing macrophage areas, NC, and artifacts.
