Carotid Doppler

A carotid doppler is an ultrasound scan that looks at the blood flow through the blood vessels in your neck.  A probe scans your neck, which transmits a moving picture of the blood flow to a TV screen.  The test takes about 10-30 minutes and is painless.  It is the same kind of scan that pregnant mothers get to see their baby during pregnancy.

The test can help the doctor to see if the blood vessels in your neck are narrowing – these blood vessels are important as they transfer blood to the brain.  The test can also help the doctor know if you require surgical treatment.  If there is a serious narrowing of the blood vessels your doctor may refer you to a surgeon, who will consider whether you should have an operation to try and reduce your chances of further strokes.  This operation is called ‘carotid endarterectomy'.
