What is a Vascular Ultrasound?Vascular ultrasound is an imaging test that uses ultrasound to take pictures of your veins and arteries. Some kinds of vascular ultrasound can also see how the blood is flowing through them. Ultrasound is sonar technology, similar to what bats use to fly. It uses the echoes of high-frequency sound waves to create a picture of what's going on inside your body. A vascular ultrasound can be used to:
- locate blockages and blood clots
- monitor blood flow after a procedure such as a stent or bypass
- examine or check for an enlarged artery (aneurysm)
- examine varicose veins
- aid in the specific placement of needles and catheters
