Venous Doppler
Venous Doppler is an ultrasound test used to check veins for clots, poor flow, or other venous problems.
When to get help quickly: This test may be urgent when deep vein thrombosis is suspected, especially if swelling and pain are new or a pulmonary embolism risk is a concern.
Common symptoms
Venous Doppler is usually requested because of symptoms such as limb swelling, pain, heaviness, redness, or concern about a clot.
When imaging helps
It helps when doctors need a quick, non-invasive way to see whether a vein is blocked or whether blood is flowing normally.
What radiology does
It is often ordered for swollen legs, suspected deep vein thrombosis, or unexplained pain in a limb.
What usually happens next
Treatment depends on the result and may include blood thinners, compression, follow-up, or urgent referral in selected cases.

- Leg Venous Doppler (DVT Scan)A leg venous Doppler is the standard test for deep vein thrombosis (DVT) — a blood clot in the deep veins of the leg. It is quick, painless, and uses sound waves to detect clots before they become dangerous.
- Leg Arterial Doppler (Peripheral Artery Disease)A leg arterial Doppler uses ultrasound to check the arteries that carry blood to your legs and feet. It is the standard test for peripheral artery disease (PAD), and it can identify narrowing or blockage before tissue is damaged.
- V/Q Scan (Lung Ventilation-Perfusion Scan)A V/Q scan is a nuclear-medicine test that compares airflow into the lungs (ventilation) with blood flow to the lungs (perfusion). It is most often used to diagnose pulmonary embolism when CT cannot be used.
