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). CTA is usually used as it's more widely available and faster (takes only several minutes). However, it does involve significant X-ray radiation and the use of contrast agents which is usually iodinated, which can cause allergic reactions, even anaphylaxis and can also cause renal failure.
