Representative optical coherence tomography (OCT) images to define nodular calcification and non-nodular calcification. a Longitudinal OCT image of calcified plaque. (A1-A4) Cross-sectional OCT images of nodular calcification defined as protruding mass with an irregular surface, high backscattering, and signal attenuation (arrow heads). Asterisk indicates wire artefact. b Longitudinal OCT image of calcified plaque. (B1-B4) Cross-sectional OCT images of non-nodular calcification defined as an area with low backscattering heterogeneous region with well-delineated border without protrusion into the lumen (arrows). Asterisk indicates wire artefact. OCT = optical coherence tomography
