    Targeted Near-Infrared Fluorescence Imaging of Atherosclerosis

    Objectives This study sought to determine whether indocyanine green (ICG)–enhanced near-infrared fluorescence (NIRF) imaging can illuminate high-risk histologic plaque features of human carotid atherosclerosis, and in coronary atheroma of living swine, using intravascular NIRF-optical coherence tomography (OCT) imaging. Background New translatable imaging approaches are needed to identify high-risk biological signatures of atheroma. ICG is a U.S. Food and Drug Administration–approved NIRF imaging agent that experimentally targets plaque macrophages and lipid in areas of enhanced endothelial permeability. However, it is unknown whether ICG can target atheroma in patients. Methods Eight patients were enrolled in the BRIGHT-CEA (Indocyanine Green ...
