The Colour Doppler is a diagnostic imaging technique widely used in medical fields to visualize blood flow through vessels and assess the health of various organs and tissues. It combines traditional ultrasound imaging with Doppler ultrasound to provide real-time visual and quantitative data on blood flow. In Colour Doppler imaging, sound waves are emitted and reflected by moving blood cells within the body, allowing the device to capture speed, direction, and turbulence of blood flow and display them in a colour-coded map. Typically, red and blue colours represent the direction of blood flow: red shows flow toward the transducer, while blue indicates flow away from it.
Colour Doppler is a non-invasive, relatively safe procedure with no ionizing radiation, making it suitable for repeated use and sensitive patients, including pregnant women. Its real-time imaging capabilities help clinicians quickly diagnose and monitor various conditions, guiding treatment plans effectively.
