MR angiography correlates well with conventional angiography for severe carotid stenosis without missing lesions; leaves open whether it can replace conventional imaging preoperatively.
Does magnetic resonance angiography accurately evaluate carotid artery stenosis compared to conventional angiography in symptomatic patients undergoing carotid endarterectomy?
Magnetic resonance angiography is highly correlated with conventional angiography for detecting severe carotid stenosis and may serve as an adequate sole preoperative imaging study in symptomatic patients.
