Why is the image of color Doppler ultrasound not in color?
The full name of color Doppler ultrasound is color Doppler ultrasound, that is, color Doppler technology is added on the basis of B-mode ultrasound. B-mode ultrasound is the basis for disease diagnosis, and it shows the shape and location of the disease and the internal structure mainly depends on it. Color Doppler is a technique that displays blood perfusion in organs and lesions, which can provide more information for the diagnosis of diseases, which is the icing on the cake. It uses different colors and brightness to distinguish the direction and speed of blood flow, so when the color Doppler function is turned on, dots of red or blue blood flow information will appear on the image, so it is called "color ultrasound" , But this function cannot be activated all the time, just turn it on when needed, otherwise the shape and location of the lesions will be difficult to clearly display, so we will ignore the other. Therefore, "color Doppler ultrasound" is black and white most of the time. At present, most of the ultrasound examination equipment in hospitals basically have color Doppler function, so you don't have to worry that you will suffer.
