- CT scan of the head
- CT angiogram (CTA)—to assess blood vessels in the brain and neck with contrast dye
- MRI of the head
- Magnetic resonance angiography (MRA)—to assess blood vessels in the head using magnetic imaging
- Arteriogram /angiogram—to locate and assess blockage or narrowing of blood vessels using contrast dye
- A carotid endarterectomy to remove the plaque deposits
- Other less invasive procedures, such as intra-arterial stenting to widen an artery
