<unk>  is a catheter-based molecular imaging technique that uses near-infrared<unk>  to detect artery wall autofluorescence (NIRAF) or<unk>  generated by molecular agents injected intravenously (NIRF) . No commercial systems based on<unk>  are currently on the market, however, significant steps forwards in<unk>  imaging technology have been made between 2010-2016. It is typically used to detect functional state of artery wall including some known high-risk features of atherosclerosis (e.g., inflammation). It is usually combined with structural imaging modalities such as<unk>  ultrasound and/or Intracoronary optical coherence tomography, to provide functional information in a morphological context.
