1. Optical coherence tomography (OCT) is an intravascular imaging technology capable of providing high-resolution, cross-sectional images of arterial structure and pathology. Often compared with intravascular ultrasound (IVUS), OCT can better identify structures of the arterial wall, such as the internal and externalelastic laminae (IEL and EEL),1,2 as well as provide precise measurement of the intimal thickness separate from the medial layer.3 Additional studies have demonstrated OCT's ability to differentiate the composition of atherosclerotic plaque into fibrous, lipid-rich, and calcified tissues with sensitivity comparable to IVUS.1,4,5 Further, with its higher resolution in the range of 10 to 20 µm (compared to 100 ...
