Tomografía por Coherencia Óptica Intracoronaria: Bases Físicas, Utilidad Clínica e Interpretación

Abstract

Optic Coherence Tomography (OCT) is an invasive imaging system based on infrared light. By using light instead of ultrasound it is possible to obtain high-resolution images of the coronary arteries as well as of implanted stents. Images analyses allow for a detailed evaluation of the coronary artery lumen and wall, thus providing information of coronary atherosclerosis and stent implantation results and complications. Herein, basic concepts of image acquisition, interpretation and clinical use are described.
