Venous Doppler Ultrasound

A venous doppler ultrasound is a test that uses sound waves to measure the flow of blood through your veins. The test is also called a “venous duplex ultrasound” or “venous ultrasound”. This test can be used to check for blood clots, blockages, or other problems in the veins of your legs. 

Why Is a Venous Doppler Ultrasound Done?

A venous doppler ultrasound may be done to:

  • Check for a blood clot in the leg (deep vein thrombosis)
  • Check for a blockage in the veins that might cause swelling or pain in the leg
  • Look for other problems with the veins in the leg, such as inflammation or a buildup of plaque 

What Happens During a Venous Doppler Ultrasound?

You will lie on your back on an exam table during the test. Your leg will be exposed above the knee. Your doctor or a trained technician will apply gel to your skin over the area being studied and then place a hand-held device called a transducer against your skin. 

The transducer uses sound waves to create images of your veins on a computer screen. The Radiologist will interpret the results and send the information to your doctor.
