non-invasive test combining ultrasound and Doppler to assess blood flow

A Duplex Ultrasound, also known as Duplex Scan or Duplex Sonography, is a non-invasive medical test that combines traditional ultrasound and Doppler ultrasound. It uses high-frequency sound waves to create images of blood vessels and measure the speed and direction of blood flow within them. This test is commonly used to diagnose conditions like blood clots, blocked arteries, and other vascular issues.
