Color Doppler Sonography is a non-invasive imaging technique used to assess blood flow and the movement of fluids within the body. It combines traditional ultrasound with Doppler technology, which measures the frequency change of sound waves as they bounce off moving objects, such as red blood cells. The resulting images show the direction, speed, and characteristics of blood flow in color, making it easier to detect abnormalities like blockages, narrowing of blood vessels, or heart valve issues.

It is widely used in cardiology, obstetrics, and vascular medicine for evaluating conditions such as deep vein thrombosis, aneurysms, and fetal health. Color Doppler is safe, provides real-time imaging, and is a valuable tool in diagnosing and monitoring various medical conditions.
