2D ultrasound is the most common ultrasound examination, which is an ordinary examination using the principle of two-dimensional imaging, and no longer performs three-dimensional imaging. In the second level A class hospital, the charge is about less than 100 yuan, and in the second level B class hospital the charge may be lower. In hospitals above the third class B level, the fee may be higher, possibly rising to between 100-200 yuan, depending on the level of the hospital. As for the specific charges, we have to combine the charges of the local hospital, and the charges of the local hospital shall prevail, and we need to consult the local hospital. The charges for 3D ultrasound or 4D ultrasound will increase accordingly, but the stereoscopic imaging effect of 4D ultrasound will be better.
