Diagram (image) Radiological Society of North America Share Print E-Mail Caption This diagram shows representative changes in carotid wall area, lumen area, and remodeling index for the ICA and CCA. Representative values of lumen and wall areas are taken from Table 1. The normal remodeling index tends to be approximately 0.4 independent of vessel size. The remodeling index increases with relatively increased atherosclerotic burden. Diagrams are not to scale.
