Elsevier Global Medical News -- The most cost-effective strategy to diagnose carotid artery stenosis for most patients with recent transient ischemic attacks or minor strokes is duplex ultrasound, followed (if the results are positive) by CT angiography. Patients with 70%-99% stenosis should then undergo carotid endarterectomy, according to a study published in the journal Radiology and based on a meta-analysis, a review of the literature, and a prospective diagnostic cohort study.
