Intravascular Optical Coherence Tomography: Comparison with Histopathology in Atherosclerotic Peripheral Artery Specimens

OCT of peripheral human arteries ex vivo characterized different atherosclerotic plaque types with a high degree of agreement with histopathologic findings. Findings were comparable to those reported for coronary arteries. OCT promises to improve understanding of the progression or regression of peripheral atherosclerosis in vivo.
