MRA

If there is doubt whether the narrowing is still patent (open to blood flow) and the patient is to be assessed for treatment, the next imaging option would either be computed tomography angiogram (CTA) or a magnetic resonance imaging angiogram (MRA).

Disadvantages of MRA

• MRA takes much longer to complete
• Over-estimates the stenosis
• More expensive and not yet as widely available
