The arterial ultrasound uses sound waves at a frequency that is higher than humans are able to hear to produce images on a monitor for the purpose of evaluating the arterial blood flow to the upper and lower extremities.

For the exam, a blood pressure cuff is applied to each of the arms or legs and a pressure is recorded for each extremity cuff. The pulse is also taken and recorded for each of the extremities. The patient may then be exercised and blood pressure recordings are repeated or an ultrasound may be performed to assess the arteries for the location and the amount of narrowing.

The procedure takes between 45-60 minutes.

Why is this test ordered?
The arterial ultrasound is able to demonstrate blocked or reduced blood flow through the major arteries of the arms and legs. It is used to evaluate:
  • Numbness and tingling sensations in the hands, arms, feet and legs
  • Sensation of fatigue and heaviness in the arms or legs
  • To investigate the possibility of thoracic outlet syndrome
What preparations are needed?
No special preparations are needed for this test.
