What Do Colours Mean on Ultrasound?
When you look at an ultrasound image, it can seem like a jumble of shades and colors. However, for those trained in ultrasound diagnostics, these colors tell an incredibly detailed story about what’s happening inside your body, particularly your blood flow. Understanding what do colours mean on ultrasound can give you peace of mind and help you feel more connected to your health journey.
Breaking Down the Colours on Doppler Ultrasound
Ultrasound imaging, especially Doppler ultrasound, is not just about seeing the shape and size of organs and tissues. It’s also about understanding how things are moving within your body—specifically blood. Doppler ultrasound adds a layer of insight by using color to show how blood flows through your vessels. These colors help doctors diagnose conditions like blockages, abnormal blood flow, or even heart issues. But what do colours mean on ultrasound? Let’s break it down.

Red and Blue
These are the two most common colors you'll see on a Doppler ultrasound, and they represent the direction of blood flow relative to the ultrasound probe. Red typically indicates blood is flowing toward the probe, while blue shows blood flowing away from it. It's not about oxygen levels in the blood as you might think from biology class; it’s purely about direction. The shades of red and blue can vary in brightness or darkness, depending on how fast the blood is moving—darker shades usually represent slower flow, while lighter or brighter shades show faster movement. For example, when assessing arteries, blood flowing quickly through them would appear as a bright shade of red if it’s moving toward the probe.
Yellow and Green
These colors represent areas of turbulent blood flow. When blood moves smoothly, it’s easy to predict how it will flow and at what speed. But when something disrupts that flow—like a blockage or a narrowing of the vessel—the flow becomes chaotic, leading to turbulence. This turbulence is often shown in yellow or green, helping doctors pinpoint potential issues like narrowed arteries, blood clots, or vessel damage.
Why Are These Colours Important?
Understanding what do colours mean on ultrasound does more than just create a pretty picture—they are vital in helping medical professionals make diagnoses and guide treatment plans. Doppler ultrasound is crucial in detecting vascular blockages, monitoring heart health, and evaluating blood flow during pregnancy, providing doctors with essential insights into the health and function of your organs and circulatory system.
