Ultrasonography (ultrasound) uses high-frequency sound waves. The sound waves are sent into the body with a special wand (transducer), and echoes from the sound waves create pictures and/or a video.
The idea for the technology came from sonar technology, which uses sound waves to find underwater objects.
Ultrasound is used in many areas of medicine. It can help diagnosis various medical problems and show blockages in your blood vessels (arteries and veins).
The test can be used alone or with other tests to help your doctor understand your medical condition.
Vascular ultrasound is also called a duplex study. It is used to check blood flow in the arms and legs.
As sound waves bounce off blood cells moving in the blood vessels, their speed is tracked. This information is used to help determine if there is a narrowing (blockage) in a blood vessel.
The test is noninvasive. It also does not use needles, dye, radiation or anesthesia.
Your doctor would like you to have a vascular ultrasound to check the blood flow to specific organs in your body.

The ultrasound can take 30 to 90 minutes. Please check-in 15 minutes before your appointment so we can complete your registration.

Your doctor will get your test results and share them with you.
