Figure 2From: Relationship among coronary plaque compliance, coronary risk factors and tissue characteristics evaluated by integrated backscatter intravascular ultrasound Intravascular ultrasound images of coronary arteries. (A) Gray scale images in systole. (B) Gray scale images in diastole at the same site as (A). (C) Integrated backscatter intravascular ultrasound images at the same site as (A) and (B). (Upper) Representative cross-sectional images that showed reduction of plaque area from diastole to systole. (Lower) Representative cross-sectional images that showed increment of plaque area from diastole to systole.Back to article page
