Venous Doppler

A venous doppler is a non-invasive ultrasound that is used to produce images of the veins. A venous doppler can estimate how fast blood is flowing by measuring the rate of change in its frequency.

Generally, a venous doppler is used to look for blood clots, or deep vein thrombosis, heart valve defects, blocked arteries, decreased blood flow, aneurysms, and narrowing of the arteries.
