No

Doctor's answer:

CDFI, which means the performance of color Doppler, refers to the result expression of blood flow detection by color ultrasound. It adopts pseudo-color coding technology, commonly using red for blood flow towards the back and blue for blood flow away from the back. The depth of color represents the speed of blood flow, commonly known as color Doppler ultrasound, abbreviated as CDFI (Color Doppler flow imaging).
