What is a vascular ultrasound?

Ultrasound is a non-invasive test that helps your doctor diagnose and treat your medical problem. By using very high frequency sound waves the ultrasound machine can form images of the inside of your body. For vascular ultrasound this involves creating images of the blood vessels within your body.

You may need to have a vascular ultrasound of your thoracic outlet because you may suffer from symptoms that affect your fingers, hands, arms or shoulders. For example; some people can get pain or weakness in their arms when performing specific tasks that require them to raise their arms.

Is there any preparation I need to undertake before my vascular ultrasound?

You will need to remove enough clothing so that the sonographer is able to access your arms, shoulders and neck.

If you require it a disposable gown can be provided.
