Carotid Ultrasound and Doppler examination is a non invasive scan of the neck arteries using high frequency sound waves to detect plaque buildup. Knowing the amount and location of blocked arteries helps determine therapy and is an important part of stroke prevention.
Peripheral Artery Doppler examination is preformed by measuring blood pressures and waveforms at multiple levels of the arms or legs. Occasionally exercise testing is added to help differentiate the pain
caused by blocked leg arteries (claudication) verses leg pain caused by nerve irritation.
Peripheral Venous Doppler detects blood clots in the arm or leg veins. This test is usually ordered for painful or swollen extremities.
