Utility of MRA and CTA in the evaluation of carotid occlusive disease.
Cervical carotid artery atherosclerotic disease is an important cause of thromboembolic stroke. Noninvasive imaging techniques have become preferred in initial diagnostic workup. We review the current approach to carotid imaging, and the clinical utility and limitations of carotid computed tomography angiography (CTA) and magnetic resonance angiography (MRA). Future directions of these modalities, including carotid plaque imaging, are also discussed.
