How to Prepare For Your Exam
What to Expect
  • What happens during the exam?
  • First, the technologist will explain the exam and may ask you historical questions that aid in obtaining a more diagnostic study. You may be asked to undress below the waist and a drape or towel may be placed over you. You will lie on a specialized table that will tilt at an angle. Gel will be spread on your leg(s) to improve the quality of the sound waves. A small handheld unit called a transducer is pressed against your skin and moved back and forth over it. A picture of the blood vessels can be seen on a video monitor. The sonographer will apply compressions at different levels down each of your legs. You will need to lie very still while the ultrasound scan is being done and you may be asked to manipulate or bend your leg at different stages of the test. Doppler sonography is performed throughout the exam and you may hear noises from the machine during this time.
