Representative optical coherence tomography images. A Normal RA with visible three-layer structure. B Concentric intimal hyperplasia in RA: the intima was of uniform thickness, being thinner or only as thick as than the media. C RA with eccentric intimal hyperplasia at 7 to 9 o’ clock positions. D microvessels (arrowheads). E Fibrous plaque (arrowhead) without lipid or calcium component. A signal-rich, homogeneous region is typical for fibrous tissue. F Lipid pool (dotted line) covered by thick fibrous cap. G–H Calcified plaque (asterisk). I Calcified protrusion (arrowhead). RA, radial artery
