color Doppler imaging

Color Doppler imaging is an ultrasound technique that visualizes blood flow within the body. It uses sound waves to detect movement of blood in vessels and then translates this information into colorful images. Different colors indicate the direction and speed of blood flow—commonly, red signifies flow towards the transducer and blue indicates flow away. This method helps healthcare providers assess how well blood is circulating, identify blockages, or detect abnormal flow patterns. It’s a non-invasive, real-time tool that provides valuable insights into cardiovascular health and blood vessel function.
