Doctor's answer:
B is a three-dimensional planar examination that obtains examination results by probing a specific cross-section. If the detected diameter is not the maximum, a similar situation may occur again. It is recommended not to worry, as the above situation arises from examination errors. Generally, fetuses in development will not experience a decrease in size. The above content is the entirety of "I don't understand the prenatal examination question and want to ask?" It is hoped that the patient can soon be free from the troubles of the disease and recover quickly, enjoying a happy and joyful life every day.
