A Doppler ultrasound (Doppler sonography) test is a noninvasive procedure that can be used in measuring your blood pressure and circulation by bouncing high-frequency sound waves off your circulating red blood cells. Thanks to the Doppler Effect, a Doppler ultrasound is capable of showing blood flow, which is something a regular ultrasound cannot do.
DOPPLER ULTRASOUND PURPOSE
A Doppler ultrasound is useful in diagnosing the following conditions: The narrowing of an artery (carotid artery stenosis), bulging arteries (aneurysms), blocked arteries (arterial occlusion), heart valve defects, congenital heart disease, venous insufficiency, blood clots, and decreased blood circulation into your legs (peripheral artery disease).
DOPPLER ULTRASOUND RISKS
A Doppler ultrasound, like a regular ultrasound, is a safe procedure. It utilizes low power ultrasound waves that will cause no adverse effects or complications on your person. Unlike a regular ultrasound, a Doppler ultrasound uses Doppler measurements to asses whether blood is moving towards or away from the probe.
DOPPLER ULTRASOUND PREPARATION REQUIRED
You don't need to prepare much when undergoing a Doppler ultrasound except for the occasions when your doctor is doing tests other than the Doppler sonography procedure. Consult your doctor for more details in regards to your preparation.
DOPPLER ULTRASOUND PROCEDURE
A sonographer (the technician handling the Doppler ultrasound equipment) presses a transducer (a small handheld device about the size of a bar of soap) over the area in your body that requires examination. He'll move the transducer against your skin and from one area to another as needed.
DOPPLER ULTRASOUND COMPLICATIONS
There are no complications associated with Doppler sonography. Just as regular ultrasound is safe for pregnant women, the Doppler ultrasound is just as safe. There are no chances for infection, swelling, hemorrhaging, and pain because the procedure is a noninvasive one.
DOPPLER ULTRASOUND SIDE EFFECTS
The Doppler ultrasound has no side effects associated with it. It's a lot safer than an x-ray, so you won't be subjected to any radiation exposure. It's also risk-free because the high-frequency sound waves used to assess blood flow and pressure are harmless to your body.
DOPPLER ULTRASOUND RESULTS
After your exam is finished, the sonographer and radiologist will discern the results of the test (i.e., how fast your blood is flowing and how high your blood pressure is). By doing so, they'll be able to report to your doctor of any discrepancies and irregularities. This will help your physician determine if you're suffering from blood clots, blocked arteries, or any other blood circulation
