A new device that combines two microimaging technologies can reveal both the detailed anatomy of arterial linings and biological activities that, in coronary arteries, could indicate the risk of heart attacks or the formation of clots in arterial stents. In their report receiving early online release in Nature Medicine, Massachusetts General Hospital (MGH) investigators describe using an intra-arterial catheter combining both optical frequency-domain imaging (OFDI) and near-infrared fluorescence (NIRF) imaging to obtain simultaneous structural and molecular images of internal arterial surfaces in rabbits.
The ability to measure both microstructural and molecular information from the same location in the artery wall could provide a much better diagnostic tool for assessing vascular pathology, information that is highly relevant for diagnosing coronary artery disease, vulnerable plaque and evaluating stent healing.
