Can the big row and the fourth dimension only do the same?

Large row deformation is mainly through the form of two-dimensional or thinking color ultrasound to check, four-dimensional is an imaging method. Large row deformation is recommended through four-dimensional color ultrasound to check, because the imaging is more clear, so you can more accurately understand the situation of the fetus. Therefore, four-dimensional is a large row deformation of an inspection method, it is necessary to achieve large row deformation through four-dimensional imaging, so the two are closely related. It is suggested to understand all kinds of information before doing big row deformation, make preparations in advance, and then check, so as to increase the accuracy of the results.
