[¹⁸F]-PBR06 autoradiography at baseline (a) and after pre-incubation with cold [^natF]-PBR06 (b) and HES anatomical sections (c) in a piece of carotid endarterectomy. A large atheromatous plaque with calcification invaded the intima and tunica media of the arterial wall (d, × 25). Immunohistochemistry showed destruction of the tunica media by the plaque (e, × 25), macrophage infiltration around the cholesterol clefts (f, × 25), and scattered T-lymphocytes (g, × 100) within the plaque. The brown bar in the upper left corner is a 1-mm scale bar
