Color Doppler is a medical imaging technique that uses Doppler ultrasound to visualize blood flow in real-time. It is often used in cardiology and vascular medicine to assess blood flow in the heart, arteries, and veins.
The technique works by emitting high-frequency sound waves into the body, which bounce back off of moving blood cells. The returned sound waves are then analyzed to determine the speed and direction of blood flow. This information is then displayed on a monitor as a color-coded map, with different colors representing blood flowing in different directions and at different speeds.
Color Doppler can be used to diagnose a range of cardiovascular conditions, including valve disorders, atherosclerosis, and blood clots. It is a non-invasive and safe technique that does not use ionizing radiation, making it a popular alternative to other imaging techniques like X-rays or CT scans.
