Patient's question:
Doctor! What is the difference between ultrasound and color Doppler ultrasound?Doctor's answer:
Ultrasound, simply put, is a high-definition black and white B-ultrasound combined with color Doppler. It not only has the advantages of two-dimensional ultrasound structural images but also provides rich information on hemodynamics. You can understand it this way: the scope of color ultrasound is broader than that of black and white B-ultrasound. A regular B-ultrasound is like a black and white photo; two-dimensional color ultrasound is not a color photo. The left image generally shows the condition of the uterus in black and white, while the right fetal image displays red and blue colors to indicate blood vessel information. Three-dimensional color ultrasound appears yellowish-brown in color, while four-dimensional B-ultrasound is like a VCR shot by a camera. Ultrasound is a medical examination item that patients often encounter during their visits. In clinical practice, color ultrasound is widely used for the diagnosis of diseases in departments such as cardiology, gastroenterology, urology, and obstetrics and gynecology.
