Duplex ultrasonography

Duplex ultrasonography is a medical imaging technique that uses high-frequency sound waves to create detailed images of blood vessels and flow. It combines traditional ultrasound, which shows the structure of tissues, with Doppler ultrasound, which measures how fast blood is moving through the vessels. This helps doctors assess blood flow, detect blockages, clots, or narrowing of arteries and veins. The procedure is non-invasive, safe, and painless, often used to diagnose vascular conditions, evaluate symptoms like swelling or pain, and guide treatment plans.
