Vascular imaging uses high frequency sound waves to evaluate blood flow through the blood vessel, including the body’s major arteries and veins in the abdomen, arms, legs and neck. At Newton Medical Center, we provide both venous studies and arterial studies.
Veins, the blood vessels that carry blood back to the heart, work against the force of gravity. The calf muscles and a system of one-way valves in the veins help maintain the flow of blood toward the heart. A variety of tests can assist in the diagnosis of venous disease:
- Pulse volume recording (PVR), with segmental blood pressure impedence – measures venous blood flow and capacity using cuffs that are placed around the leg to monitor blood as it pulses through the blood vessels by recording changes in the volume of air within the cuff
- Photoplethysmography (PPG) – uses infrared light to assess blood flow near the surface of the skin. Light waves create a picture of what is taking place in the veins.
- Venous duplex study – an imaging (ultrasound) test of your major leg or arm veins to determine whether blockage or thrombus (clot) is present. Slight compressions are done on the areas being imaged, and the blood flow is sampled at designated locations.
- Vein mapping – the process of locating, marking and measuring veins in the arms or legs before bypass surgery or hemodialysis access
Arteries, which carry blood away from the heart, can become thick and less elastic over time, diminishing blood flow to the rest of the body. We provide a variety of tests to diagnose arterial diseases:
- Arterial duplex imaging – uses two types of ultrasound, standard ultrasound and Doppler ultrasound, to produce two-dimensional images of the arteries and view and measure blood flow
- Arterial pulse volume recording with segmental blood pressures (arterial PVR or Doppler) – measures blood volume changes using cuffs placed at multiple locations along the leg
- Skin perfusion – evaluates potential for healing by taking a blood pressure reading of very small arteries, called capillaries, in the leg or the foot
- Vasodilation – measures blood pressure at rest and after mild exercise using blood pressure cuffs placed on the legs
Preparing for a Vascular Ultrasound at Newton Medical Center
- Wear comfortable, loose-fitting clothing
- Clothing and jewelry may need to be removed in the area to be examined and you may be asked to wear a gown during the procedure
- Fasting may be required for certain exams
Vascular Ultrasound Results
Newton Medical Center’s radiologists are experts in supervising and interpreting radiology examinations. They will analyze your vascular ultrasound images and send a signed report to your primary care physician or the physician who referred you for the exam. He or she will discuss the results with you.
