The difference between two-dimensional three-dimensional color Doppler ultrasound

The difference between two-dimensional, three-dimensional and four-dimensional color Doppler ultrasound lies in that for ultrasound doctors, two-dimensional ultrasound is the most important diagnostic method. According to the images of two-dimensional sections, we can know what the lesions look like and the surrounding relations. Therefore, the systematic screening of fetuses at this stage, commonly known as large row abnormalities, mainly relies on two-dimensional ultrasound. There are many misunderstandings. Non-professionals cannot understand two-dimensional ultrasound, but they can understand three-dimensional and four-dimensional stereoscopic images and mistake them for three-dimensional and four-dimensional images. It is easier to find abnormalities than two-dimensional, and it is also easy to be misled by media hype. In fact, three-dimensional and four-dimensional ultrasound is only used to supplement diagnostic information that cannot be seen in two-dimensional, but it must not replace two-dimensional ultrasound. Therefore, do not be confused by the names of three-dimensional, four-dimensional and tall.
