A Doppler Ultrasound is a non-invasive test that uses high-frequency sound waves (ultrasound) to measure the amount of blood flow through your blood vessels. A Doppler ultrasound is a risk-free and pain-free procedure that requires little preparation.
The test provides your doctor with important information about the flow of blood through your major arteries and veins. It can also reveal blocked or reduced blood flow through narrowed areas in the arteries, which could eventually lead to a stroke.
A Doppler Ultrasound differs from a regular ultrasound in that it uses high-frequency sound waves to measure the blood flow of your arteries and veins, whereas an ultrasound only produces an image.
How it works
A Doppler Ultrasound procedure is painless and non-invasive. After you are positioned on the examination table, the radiologist or sonographer will apply some warm water-based gel on your skin and then place the transducer firmly against your body, moving it back and forth over the area of interest until the desired images are captured. There is usually no discomfort from pressure as the transducer is pressed against the area being examined.
Before your Doppler Ultrasound
There is little or no special preparation for this procedure. We provide general guidelines below to follow before and during your exam.
- Register with our staff at the front desk.
- You will be asked to put on a comfortable gown.
- Be prepared to remove certain items like watches, necklaces and certain types of clothing that contain metal objects such as zips, as these items may interfere with the quality of the image.
- For all examinations we ask that you bring along any previous imaging you have.
During your Doppler Ultrasound
- The technologist will introduce themselves and inform you of any additional information that is needed.
- The procedure is painless and you won't feel a thing.
- You will lay down on an examination bed for most exams or sit for certain exams.
After your Doppler Ultrasound
- You may return to your regular daily activities.
- The results of your doppler ultrasound will be made available to your physician within 24 hours.
