Intra-arterial catheter for simultaneous microstructural and molecular imaging in vivo

The future of imaging is the integration of function and anatomy. Hongki Yoo et al. have successfully done just that by combining two existing intravascular imaging techniques into a single catheter-based system. Their dual-modality intra-arterial catheter uses a combination of optical frequency domain imaging and near-infrared fluorescence imaging to simultaneously provide molecular information in the context of the surrounding three-dimensional microanatomy of the artery wall.
