Carotid Doppler ultrasound £260

Do I need a carotid Doppler ultrasound?

The carotid Doppler ultrasound is used to assess your risk of stroke. You may be at increased risk if one or more of the following applies to you:

Family history of stroke
High blood pressure
Known heart disease
High cholesterol
A smoker
Heavy alcohol consumption
Overweight

The assessment of stroke risk using ultrasound

Each year over 130,000 people in England and Wales have a stroke. Of those about a third are likely to die within the first 10 days, about a third are likely to make a recovery within one month and about a third are likely to be left with a long-term disability.

The brain is supplied with blood by the carotid arteries in the neck. Fatty deposits (plaque) laid down in the wall of these arteries can sometimes build up and obstruct the blood flow. Stroke occurs when either a clot occurs and stops the blood supply to the brain, or blood vessels around the brain burst causing bleeding. These both cause damage and destruction to the brain tissue, and can result in paralysis, loss of cognitive function and ability to speak, read or write, or in some cases death.

The carotid Doppler ultrasound is a painless and non-invasive procedure that precisely measures the extent of thickness of any plaque build-up within the carotid arteries. Lifestyle changes or medication may be recommended for any narrowing (stenosis) that is detected, or in more severe cases a surgical procedure to remove the blockage.

The actual time you spend in the scanner is about 10 minutes. Further details can be found in the Your Visit section.

Because of the similarities between the causes of heart disease and stroke, those with known atherosclerosis (heart disease) are automatically at increased risk of stroke. It may therefore be worth considering combining this ultrasound with an EBCT heart scan for a more comprehensive investigation. Combining Scans

Do I need to prepare for the scan?
