Visual analysis versus semi-automated GSM colour mapping of the carotid plaques: which method predicts better the presence of lesions on MRI?

Problemstellung: Plaque morphology analysis determined either by a visual or a computerised analysis, represents an important step in the assessment of the embolic risk of carotid stenosis. We sought to compare these two methods and to determine their ability to predict the presence of lesions on MRI. Patienten und Methode: Consecutive 50%-99% carotid stenoses from symptomatic or asymptomatic patients were evaluated. Visual analysis of the echogenicity and of the surface of the plaque was performed (criteria established by Geroulakos et al). GSM colour mapping of the plaque was established by means of a semi-aut…
