What is Ultrasound and Color Doppler?
Ultrasound (ultrasonography) is a diagnostic technique that uses high-frequency sound waves, beyond human hearing, to create images of the body’s internal structures. When these sound waves bounce off tissues or organs inside the body, the ultrasound machine converts them into images that a doctor can use for analysis. Ultrasound is often used to examine pregnant women to monitor fetal growth, but it is also used in various medical disciplines, including cardiology, gastroenterology, gynecology, and others, to diagnose various problems or diseases.
Color Doppler (or Doppler ultrasound) is a special type of ultrasound examination that allows the visualization of blood flow in blood vessels and evaluates the speed of that flow. This technique uses the Doppler effect, which occurs when sound waves reflect off moving red blood cells. Color Doppler imaging adds color to the ultrasound image to clearly show blood movement: blue is used to show blood moving toward the ultrasound probe (called “downstream flow”), while red is used for blood moving away from the probe ( the so-called “upstream flow”). This technique is essential for the diagnosis of vascular diseases, as well as for monitoring blood flow in various organs and tissues of the body.
