ABSTRACT
Ultrasound imaging is recognized as an accurate method for the diagnosis and quantification of carotid artery stenosis.1-4 Duplex scan and colour flow Doppler provide information concerning not only the degree of stenosis, but also the features and structure of the plaque.5-7 Subsequent studies comparing conventional angiography with Duplex scanning in the evaluation of carotid plaque morphology have confirmed the superiority of echography in this area.8,9
Therefore, ultrasonography may potentially be used in the evaluation of carotid stenosis, the analysis of the plaque structure before carotid stenting and for during follow-up.
