A PVR (Pulse Volume Recordings) study is a non-invasive vascular test in which blood pressure cuffs and a hand-held ultrasound device (called a Doppler or transducer) are used to obtain information about arterial blood flow in the arms and legs. Non-invasive means the procedure does not require the use of needles, dyes, radiation or anesthesia. The blood pressure cuffs and Doppler are used to determine the presence, severity and general location of peripheral arterial occlusive disease.
A PVR also may be called a vascular study or Doppler segmental pressure study. It is more detailed than an ABI and can localize where in the leg blockages are located.
Why do I need this test?
Your physician has recommended that you have this test to evaluate the blood flow in your arms and legs. This test is used to evaluate the presence of peripheral arterial disease. It is a useful test to see if exertional leg pain is caused by spinal stenosis or arterial disease.
How Should I Prepare for the Test?
- Do not smoke or participate in strenuous activities for 24 hours before the test.
- You may take your usual medications.
- There are no special dietary guidelines; you may eat and drink as you normally would.
