Färgdopplerbilder
Färgdopplerbilder, often referred to as color Doppler imaging, is an advanced ultrasound technique used to visualize and assess blood flow within the body. This technology builds upon standard ultrasound by adding a color overlay to the grayscale image, representing the direction and velocity of blood. Typically, red indicates blood flow towards the ultrasound transducer, while blue signifies flow away from it. Brighter shades of red or blue suggest faster blood flow, whereas dimmer shades denote slower flow.
The primary purpose of färgdopplerbilder is to detect abnormalities in blood circulation. This can include identifying
