CT Angiography of the Carotid Arteries

Computed Tomography (CT) angiography of the carotid arteries is one of the most effective and accurate diagnostic methods for evaluating the arteries that supply blood to the brain. Thanks to high-resolution imaging, CT angiography can detect narrowing (stenosis), thrombosis, aneurysms, atherosclerotic plaques, and other vascular abnormalities. The examination is non-invasive and provides detailed visualization of the vascular system without the need for catheter-based angiography.

If you experience dizziness, sudden headaches, ringing in the ears, fainting, or impaired coordination, your physician may recommend this examination. It is also commonly prescribed for patients with suspected ischemic stroke, chronic cerebrovascular insufficiency, or for assessment of cardiovascular risk.

What Conditions Can CT Angiography of the Carotid Arteries Detect?

  • Narrowing of the vessels (stenosis), which may impair blood flow to the brain.
  • Atherosclerotic plaques that increase the risk of thrombosis and stroke.
  • Aneurysms — abnormal dilations of the arterial walls that may rupture.
  • Blood clots or emboli that can block the vessel lumen and cause acute disruption of cerebral circulation.
  • Vascular malformations — congenital abnormalities of blood vessel structure.
