A Doppler ultrasound is a noninvasive test that can be used to estimate the blood flow through your blood vessels by bouncing high-frequency sound waves (ultrasound) off circulating red blood cells. A regular ultrasound uses sound waves to produce images, but can't show blood flow.
DOPPLER ULTRASOUND SCAN
It is important to prepare your legs for treatment
A Doppler ultrasound may help diagnose for example poorly functioning valves in your leg veins, which can cause blood or other fluids to pool in your legs (venous insufficiency) or decreased blood circulation into your legs (peripheral artery disease).
A Doppler ultrasound test may also help your doctor check for injuries to your arteries or to monitor certain treatments to your veins and arteries.
