Noninvasive evaluation of carotid artery stenosis: indications, strategies, and accuracy

Neuroimaging Clin N Am. 2005 May;15(2):351-65, xi. doi: 10.1016/j.nic.2005.06.005.


Carotid artery occlusive disease is an important stroke risk factor and accounts for a significant proportion of stroke morbidity and mortality. In this article we survey the major clinical trials related to stroke risk in symptomatic and asymptomatic patients who have internal carotid artery (ICA) stenosis; techniques for noninvasive screening of ICA stenosis including ultrasound, MR angiography, and CT angiography; and evolving algorithms for ICA evaluation. We comment on current interest in plaque morphology as a risk factor for stroke.
