Carotid Doppler Test

Jump to Tests

Carotid ultrasound produces images of the carotid arteries, which carry blood from the heart to the brain. Plaques, made of fat, cholesterol, calcium, and other substances circulating in the blood, narrow the carotid arteries. It is frequently done to examine the narrowing (stenosis) of the carotid artery, a condition that elevates the risk of Stroke

Carotid Doppler is recommended for patients preparing for coronary artery bypass surgery. Some risk factors for which the test is done are as follows: 

  • Diabetes
  • Elevated blood cholesterol
  • Hypertension 
  • Recent transient ischemic attack (TIA) or stroke
  • Unusual sounds in the carotid arteries were detected using a stethoscope
  • Coronary artery disease
  • Hardening of the arteries
  • A family history of stroke or heart disease

Carotid Doppler test helps to see and evaluate:

  • blockages to blood flow (such as clots)
  • narrowing of vessels
  • tumors and congenital vascular malformations
