Optical coherence tomography (OCT) has recently been developed as a high-resolution intravascular imaging modality, detecting small abnormal structures in the coronary lumen that could not be visualised by intravascular ultrasound (IVUS).
A 77-year-old man died with acute myelogenous leukemia. After he died, the coronary artery was imaged by OCT (ImageWire; LightLab Imaging, Westford, MA, USA) and IVUS (Atlantis SR Pro, 40 MHz; Boston Scientific, Natick, MA, USA).
