    Optical Technology Stepping Forward ― Utility of Intracoronary Optical Coherence Tomography ―

    I ntravascular optical coherence tomography (OCT) is a light-based imaging modality that enables detailed visualization of the intraluminal structures in coronary arteries. High-resolution (10–20μm) cross-sectional images are generated by measuring the echo time delay and intensity of light that is reflected or backscattered from the internal structures in tissues.1,2 OCT is clinically useful during percutaneous coronary intervention (PCI) to assess lesion severity, optimize stent implantation, and characterize atherosclerotic plaques, including the identification of thin-cap fibroatheroma (TCFA) and lipid-rich plaques, which are reportedly responsible for periprocedural complications. OCT can also be used to assess the mechanism for ...
