What Is a Doppler Ultrasound?

Your cardiovascular system circulates blood throughout your entire body. Blood vessels are the veins and arteries that carry blood from your heart to your other organs and limbs. Good circulation is necessary to stay healthy. When narrowed or blocked blood vessels interrupt this system, they can cause serious problems. Limited blood flow or blockages can lead to strokes, deep vein thrombosis (DVT) and other life-threatening conditions.

The purpose of a Doppler ultrasound is to give your doctor a better look at the condition of your veins, allowing your physician to identify the cause of your circulatory problems. These noninvasive exams use sound waves to create images of your veins, enabling doctors to examine blood flow and pressure throughout your body. If there is a clot, plaque buildup or another issue, it will appear on the ultrasound. Your doctor can use these images and relevant data to make a diagnosis or establish a treatment plan.

How Does a Doppler Ultrasound Work?

A Doppler ultrasound is a no-pain, no-risk alternative to more invasive tests. This diagnostic exam is painless, often lasts under an hour and has no side effects.

During a Doppler ultrasound, a technician (known as a sonographer) uses a wand-like tool called a transducer. The transducer emits sound waves that help create images of your blood vessels. Depending on the artery under examination, the sonographer runs the transducer over your legs, arms, neck (for carotid Doppler ultrasounds) or other body parts. The sound waves bounce off the vein and the transducer records the returning echo, turning it into a visual graphic.

Uses of a Doppler Ultrasound

The images created with a Doppler ultrasound allow doctors to measure the amount of blood flowing through your veins. This information is valuable for many reasons. Venous Doppler ultrasounds are primarily used to show blockages or reduced blood flow in the legs and sometimes arms. These blockages can cause serious harm, including a DVT, if left untreated. Cardiologists can identify and monitor your condition using ultrasound images and determine the path forward.

Your doctor can also use arterial Doppler ultrasounds to identify blood clots, circulation problems, plaque accumulation, insufficient blood flow and poorly functioning valves in any blood vessel. These issues can pose a serious threat to your cardiovascular health and might lead to stroke or another dangerous condition. With an ultrasound, your doctor can examine the risks and calculate the best course of action.

Doctors use the data from Doppler ultrasounds to identify underlying conditions, determine the proper treatments and reduce your risk of stroke and other issues. They might suggest an ultrasound if you’re at risk of stroke or show signs of poor circulation.
