Color ultrasound is short for color Doppler ultrasound, and B ultrasound is short for B-Mode Ultrasound. Color ultrasound and B ultrasound are two completely different instruments, rather than people imagine a simple color difference similar to color television sets and black and white television sets, color ultrasound is not color B ultrasound. The main technical indicators of color ultrasound, such as the number of probe wafers, the number of imaging channels, the dynamic range of imaging, the host's processing power and depth, etc., are much higher than that of B ultrasound, so it can significantly improve the image resolution, and it can detect smaller lesions at an earlier stage to improve the early diagnosis of the disease, and it can show the details of the periphery of the lesion and the internal changes much more clearly, so as to improve the accuracy of the diagnosis.
Color ultrasound has the function of Color Doppler Flow Imaging, which can show the anatomical structure of blood vessels in the lesion area, the direction of blood flow, the speed of blood flow, and changes in the state of blood flow, which can significantly improve the ability to identify the disease and improve the accuracy of diagnosis.
Color ultrasound with tissue harmonic imaging function, can significantly reduce obesity, gas and other artifacts interference, improve image clarity. Color ultrasound with contrast agent harmonic imaging function, can be acoustic imaging, more in-depth examination and study of lesions.
Some color ultrasound also has some special functions, such as myocardial motion velocity analysis, four-dimensional imaging, etc., which can provide more in-depth quantitative analysis of lesions. Therefore, color ultrasound can detect lesions earlier and can more accurately make differential diagnosis of lesions, significantly improving the accuracy of diagnosis, while the rate of leakage and misdiagnosis of ultrasound is significantly higher than that of color ultrasound.
