Abstract: This article presents the results of ultrasound assessment of the morphology of carotid atherosclerotic plaques using duplex scanning and offline videodensitometric analysis of 160 carotid atherosclerotic plaques. Ultrasonic densitometry analysis of images may be used to identify vulnerable and potentially unstable lipid-rich carotid plaques, which are less echogenic in density than stable or asymptomatic, fibrotic plaques. Atherosclerotic plaques with higher values of energy and greater homogeneity should be more stable and less prone to rupture.
