From: Quantitative assessment of carotid plaque surface irregularities and correlation to cerebrovascular symptoms

Figure 1

Two plaques of markedly different surface irregularity indices: (a) a symptomatic plaque with an SII of 2.25 radians/mm; and (b) an asymptomatic plaque with an SII of 1.57 radians/mm. The plaque surface is the boundary between the plaque and the arterial lumen (where the pink and green dashed lines overlap). (a) is also a plaque qualitatively classified as having an irregular surface, while (b) is a plaque qualitatively classified as having a smooth surface.
