Vascular ultrasound provides pictures of the body's veins and arteries.
A Doppler ultrasound study may be part of a vascular ultrasound examination.
Doppler ultrasound is a special ultrasound technique that evaluates blood velocity as it flows through a blood vessel, including the body's major arteries and veins in the abdomen, arms, legs and neck.
Common uses of Vascular Ultrasound
- Help monitor the blood flow to organs and tissues throughout the body.
- Locate and identify blockages (stenosis) and abnormalities like plaque or emboli and help plan for their effective treatment.
- Detect blood clots (deep venous thrombosis (DVT) in the legs or arms.
- Determine whether a patient is a good candidate for a procedure such as angioplasty.
- Evaluate the success of procedures that graft or bypass blood vessels.
- Determine if there is an enlarged artery (aneurysm).
- Determine the source and severity of varicose veins.
- Doppler ultrasound images can help the physician to see and evaluate:
- Blockages to blood flow (such as clots).
- Narrowing of vessels (which may be caused by plaque).
- Tumors and congenital malformation.
