Vascular studies are noninvasive (the skin is not pierced) procedures that are used to evaluate the blood flow in arteries and veins. A microphone like instrument (transducer) is placed on the skin at certain locations and angles, allowing ultrasonic sound waves to move through the skin and other body tissues to the blood vessels, where the waves echo off of the blood cells. These reflected waves are picked up by the transducer and are sent to an amplifier, which makes the ultrasonic sound waves audible.
Here are some of the more common vascular studies that can be performed by Empire Medical:
Trans-Cranial Doppler: uses ultrasound technology via a Doppler transducer to study the velocity of blood flow to the brain’s blood vessels. It is used for the diagnosis of brain hemorrhage, blockages in the brain circulatory system and stroke risk. As non-invasive tests, there is generally no preparation required for or after effects experience from the vascular studies performed at Empire Medical.
