Venous Doppler Ultrasound/Sonogram

About this Test

This test examines the veins in one or both of your legs or arms. Pictures of these veins are taken with sound waves, not x-rays.

Why this Test is Done

You may have had a recent injury or surgery that is causing pain, swelling, or redness in your legs or arms, or the pain, swelling, or redness may have appeared suddenly. These symptoms could be caused by a blood clot forming in the veins. The sonogram will identify blood clots in the veins that may decrease the blood flow.

Before the Test

You may eat, drink, and take medication as you usually do.

During the Test

You will be asked to remove pants or hosiery so that direct contact with the skin can be made. You will be asked to lie on an exam table. Warm gel will be applied to your leg (or arm). This helps to optimize the images. Pictures will be seen on a computer screen during the exam. Noises will be heard throughout portion of the test. The technologist will warn you of these before they happen.

After the Test

You may be asked to wait while the images are reviewed.

Test Results
