An ultrasound is a non-invasive diagnostic test, not requiring the use of anesthesia or needles, to examine the circulation of blood vessels (arteries and veins) within the body and identify potential issues. It is especially important if you have any of the Peripheral Artery Disease (PAD) risk factors, such as high blood pressure, diabetes, high cholesterol, family history or smoking.
During an ultrasound, high frequency sound waves, or ultrasound waves, are bounced off tissues in the body by using a special device, and are then reflected back to the ultrasound machine. These sound waves are then converted into an image and displayed on the computer screen. The technologist evaluates blood flow through the vessel, looking for narrowed areas (blockages) in the arteries and blood clots in the veins.
