Ultrasound and color ultrasound are both commonly used in clinical practice, and ultrasound is used to detect abnormalities in the internal organs of the body through the transmission of ultrasound. Color ultrasound is the addition of Doppler technology to B-ultrasound. This technology not only detects the shape and size of the organs, but also the blood flow supply to the organs. In the clinical setting, the type and nature of the disease can be initially clarified by observing the blood flow supply to the organ. Therefore, color ultrasound is used more than B-ultrasound in clinical practice. It is also currently recommended that when choosing a means of examination, color ultrasound should be chosen for examination whenever possible to avoid delaying the diagnosis and treatment of the disease due to the limitations of B-ultrasound examination.
