Lower Limb Arterial Ultrasound
Ultrasound of the leg arteries involves looking at the blood supply from the heart to the arteries in the leg(s). This is a non invasive test that gives your doctor information needed in diagnosing peripheral arterial disease.
Your doctor may request an ultrasound of the arteries (vessels that carry blood from your heart) in your leg(s). Ultrasound is a procedure that uses sound waves to “see” inside your body. This procedure uses color to map the arteries in your leg(s) to identify narrowing of your vessels that may be causing leg pain when walking, resting leg pain, foot, ankle, heel or toe ulcers, or skin discoloration.

We want to make your waiting time as pleasant as possible. Please consider bringing your favorite magazine, book or music player to help you pass any time you may have to wait.
Please leave your jewelry and valuables at home.
During Your Exam
The vascular technologist will explain your exam and answer any questions you may have.
Your procedure will be performed with you lying on the examination table on your back with your hands at your sides or on your stomach.
The technologist will apply warm gel to your leg(s).
A transducer, a small, microphone-like device, will be placed over various locations on your leg(s).
Blood pressure readings will be taken of your ankles. You will not feel any pain; however you will feel mild pressure from the blood-pressure cuff and the transducer.
Sound waves will bounce off the muscle and tissue in your body and off the blood moving in your arteries. This creates “echoes.” The echoes are reflected back to the transducer. A television monitor shows images as the transducer converts the echoes to electronic signals.
These images may be viewed immediately or photographed for further study.
You will hear unusual sounds as the technologist views and records the blood flowing through the arteries in your leg(s).
Your exam will take approximately 60 minutes.
