Color Doppler ultrasound can display color images on the screen, which can directly calculate the speed of blood flow and measure the pressure difference between the front and back of a local narrow lumen in the heart and large blood vessels;
For organs and lesions, it can evaluate the vascular distribution of the organs and the perfusion of the lesions, providing more information for diagnosis and differential diagnosis.
The popularization of color Doppler ultrasound has greatly improved the level of ultrasound diagnosis, which is the second technological leap of ultrasound after gray-scale ultrasound.
