The correlation between calcification in carotid plaque and stroke: calcification may be a risk factor for stroke.

Abstract

The quantity and shape of the calcification, and the presence of neovascularization adjacent to the calcification have certain effects on the stability of plaques. Multiple calcifications, nodular calcification, and neovascularization near calcification may cause plaque rupture and therefore might be risk factors for stroke. Our results suggest that the joint use of two-dimensional ultrasound and CEUS can provide comprehensive information on plaques to assess their stability.
