Magnetic resonance angiography can select patients for endarterectomy

Magnetic resonance angiography is sufficiently accurate to detect patients with 70-99% carotid stenosis. Westwood et al (p 198) conducted a systematic review to compare the diagnostic performance of magnetic resonance angiography with conventional angiography in patients with symptomatic carotid stenosis. They found that the technique was highly sensitive and specific in detecting the degree of stenosis that identifies suitable candidates for surgery. Magnetic resonance is less invasive than conventional angiography.
