↵1-150 Plaque morphology classified by using ICUS criteria.Soft plaque—more than 80% of the plaque composed of tissue with an echogenity lower than the echogenity of the adventitia (arc of lesion calcium < 90%).Intermediate plaque—more than 80% of the plaque area composed of tissue producing echoes as bright or brighter than the adventitia (arc of lesion calcium < 90%).Calcified plaque—plaque involving bright echoes with acoustic shadowing accompanying more than 90° of the vessel wall circumference.4
↵1-151 Plaque density derived from density measurements performed by multi-slice computed tomography (HU, Hounsfield units).
