When to do four-dimensional ultrasound

Ultrasound is to check whether the structure of the organ is abnormal through the transverse and longitudinal sections of the tissue and organ. Therefore, all ultrasound examinations are judged on the basis of two-dimensional sections; three-dimensional ultrasound is to construct the three-dimensional structure of the organ through computer three-dimensional imaging; real-time three-dimensional ultrasound is four-dimensional ultrasound. Generally speaking, if you want to distinguish whether the organ structure is normal, you only need to do two-dimensional ultrasound; if you need to see the whole three-dimensional structure, you should do three-dimensional ultrasound; To see the trend of blood flow, need to do four-dimensional ultrasound, such as cardiac vascular dysplasia.
