Doppler Ultrasonography

Doppler Ultrasonography is a medical imaging technique that uses sound waves to visualize blood flow in the body. It measures how the frequency of these sound waves changes when they bounce off moving objects, like red blood cells. This change, known as the Doppler effect, helps doctors assess how well blood is circulating in veins and arteries. It's commonly used to diagnose conditions related to blood flow, such as blockages or blood clots, and is non-invasive, meaning it doesn't require any surgical procedures or the introduction of instruments into the body.
