Coronary CT Angiography in the Quantitative Assessment of Coronary Plaques
Figure 2
Example of lesion with positive remodelling on 320-row CT angiography and corresponding findings on virtual histologic intravascular ultrasound image. Curved multiplanar reconstruction of left anterior descending coronary artery showing a large plaque in the proximal segment of the vessel (a). The diameter of the vessel at the plaque site (arrow) is larger compared to the diameter at the reference sections (1, 2), indicating the presence of positive remodeling. Corresponding longitudinal (b) and cross-sectional (c) virtual histologic intravascular ultrasound images demonstrate an outward-remodeled lesion, with a large plaque burden (69%) and a large amount of necrotic core (19%) (red areas), corresponding to a thin-capped fibroatheroma lesion.
