Color ultrasonography is a type of ultrasonography.2. Ordinary ultrasonography produces a two-dimensional image, which is relatively abstract and only a professional ultrasonographer can distinguish its contents; the image during color ultrasonography is relatively clear and intuitive, and in color ultrasonography, blood flow can be observed to the examined area, especially for suspicious occupying lesions, through color ultrasonography Color ultrasonography can be used instead of normal ultrasonography.4. Color ultrasonography also includes three-dimensional ultrasonography and four-dimensional ultrasonography. These examinations also belong to color ultrasound examination, and the examination results are more intuitive and reliable.
