title: Intravascular near-infrared fluorescence molecular imaging of atherosclerosis.
abstract: Novel imaging modalities are required to better identify vulnerable atherosclerotic plaques before their dire consequences of myocardial infarction, sudden death, and stroke. Moving beyond traditional diagnostic methods, the field of molecular imaging offers an innovative approach to report upon critical in vivo biological features of high-risk plaques. Molecular imaging employs engineered, targeted imaging agents in conjunction with sophisticated, high-resolution detection systems. While various modalities have been investigated for this purpose, intravascular near infrared fluorescence imaging (NIRF) strategies are uniquely poised to provide high-resolution readouts of human coronary artery plaques. To date, preclinical animal studies have demonstrated feasibility of both standalone NIRF intravascular imaging as well as dual-modality approaches detecting inflammation and fibrin deposition in coronary-sized arteries. This translatable catheter-based approach is positioned to advance the identification of biologically vulnerable coronary plaques and coronary stents at risk of thrombosis.
