Autoradiographical assessment of inflammation-targeting radioligands for atherosclerosis imaging: potential for plaque phenotype identification

Abstract

Radioligands targeting inflammatory cell markers showed different levels of binding in atherosclerotic plaques and among plaque phenotypes. Different radioligands might be used for plaque detection and discerning early from vulnerable plaque. [¹¹¹In]In-EC0800 and [¹¹¹In]In-DANBIRT appear most suitable for plaque detection, while [⁶⁷Ga]Ga-Pentixafor and [¹¹¹In]In-DOTA-JR11 might be best suited for differentiation between plaque phenotypes.
