Patient's question:
Hello:I am 7 months pregnant. I have had 4 ultrasound scans already. Is that too many? Can I still have one when I'm close to giving birth? I heard that doing too many ultrasounds can be harmful to the fetus, and I really regret having so many done.
Doctor's answer:
It has little impact because ultrasound uses sound waves to transmit, resulting in minimal radiation. During the early stages of pregnancy, when cells are dividing and developing, the heat generated by the ultrasound probe contacting the abdomen for a brief moment can be relatively high, and the baby may not adapt well to it. Therefore, if it is confirmed that the fetus is safe, it is best not to perform frequent ultrasound examinations.
