"What are vascular studies?
Vascular studies are tests that check the blood flow in your arteries and veins. These tests are noninvasive. This means they don’t use any needles.
Vascular studies use high-frequency sound waves (ultrasound) to measure the amount of blood flow in your blood vessels. A small handheld probe (transducer) is pressed against your skin. The sound waves move through your skin and other body tissues to the blood vessels. The sound waves echo off of the blood cells. These echoes are then sent to a computer and seen on a screen as images or video.
Vascular studies may use one of these special types of ultrasound technology:
Doppler ultrasound. This allows a healthcare provider to see blood flow through arteries and veins. The amount of blood pumped with each heartbeat is a sign of how large a vessel’s opening is. A Doppler ultrasound can also find abnormal blood flow in a vessel, which may mean there is a blockage.
Color Doppler. This is an enhanced form of Doppler ultrasound. It uses different colors to show the direction of blood flow."
