"Doctor, am I doing a color ultrasound examination? Why does it look black and white?" This is the "soul torture" that ultrasound doctors encounter almost every day. So, what is a color ultrasound? Is it a color B-ultrasound just like a color TV? As a senior "Superman", I will answer your questions here. 1. What is Color Doppler Ultrasound? Color Doppler ultrasound is the abbreviation of color Doppler ultrasound, which is a non-invasive imaging method that uses color Doppler ultrasound to examine various organs of the human body. It usually integrates multiple functions such as B-mode ultrasound, M-mode ultrasound, spectral Doppler technology, and color Doppler blood flow imaging. It is a more advanced imaging diagnostic technology developed on the basis of B-mode ultrasound. Therefore, B-ultrasound (that is, black-and-white ultrasound) is only a basic function included in the color Doppler ultrasound instrument, and it can also be said to be the earliest color Doppler ultrasound. 2. Why does the color Doppler ultrasound have color? First of all, the basic principle of ultrasonic diagnosis is to transmit ultrasonic waves to the human body through an ultrasonic device. After the ultrasonic waves encounter different tissues and organs of the human body, part of the ultrasonic waves will be reflected back to the ultrasonic device, and images will be displayed by utilizing the difference in echo signals between different tissues. Among them, the B-ultrasound displays the echo signals of different tissues in the mode of grayscale (brightness), so the image is displayed on the screen in the mode of light and dark (black and white), and the first English letter of brightness is B, Therefore, it is called B-ultrasound; color Doppler ultrasound is based on B-ultrasound and uses the Doppler effect of ultrasound to detect high-speed moving tissues in the human body (mainly the heart and blood vessels), and superimposes them on the B-ultrasound image in the form of color coding In order to display the blood flow of the tissue in "color" on the B-ultrasound black-and-white image; in short, the color of the color Doppler ultrasound is for the blood flow signal imaging of the tissue or lesion, rather than the color display of the entire display screen. In other words, for tissues or lesions with inconspicuous blood flow, color Doppler ultrasound can not show color. To sum up, in clinical work, doctors first use "B-ultrasound" to observe the morphological structure of organs or diseased tissues, and then use "color Doppler ultrasound" to detect the blood flow inside and around the lesion, and can measure the blood flow velocity, Spectrum and other parameters are analyzed, which is of great benefit to the characterization of lesions.
