Which hospital in Yantai can do four-dimensional B-ultrasound? How to make an appointment for online registration?

Only Yuhuangding Hospital in Yantai can do it, and a * * * is 280 yuan, which can be done most clearly in about six or seven months. 1 B ultrasound belongs to the category of ultrasound, so it is unscientific to say "radiation". But B-ultrasound is really bad for human body, which is true. But its ultrasound only stays in place for more than 15 minutes, which will really damage the fetus. So in theory, no matter what kind of ultrasound, as long as it is solved in a short time, it will not leave an impression. Generally, it is not good to do B-ultrasound regularly within 3 months of pregnancy, but after 3 months, it will basically be fine. Summary: Based on the above two points, it doesn't matter what ultrasound is used, whether it is three-dimensional or four-dimensional. The key lies in frequency, times and snapshots, as long as the photo interval is longer. It won't be like an x-ray, so don't worry too much. But don't listen to doctors, they all get a commission. You need to know what you are doing! Finally, I wish you a healthy baby.
