Patient's question:
Medical Description: 22 weeks pregnant, I have had four ultrasounds so far, and there will be a total of five after two more weeks. Additionally, I understand that at least two more ultrasounds are required in the later stages of pregnancy. This means I might have to have seven ultrasounds throughout my entire pregnancy. Is this too many? Will it affect the baby? How many ultrasounds are recommended during pregnancy?Previous Treatment and Effect: At 40 days of pregnancy, due to abdominal pain, I had an ultrasound at the Central Hospital, which showed no abnormalities. At 50 days of pregnancy, the abdominal pain did not improve, so I had another ultrasound at the Provincial Hospital, which also showed no abnormalities. At 17 weeks of pregnancy, I had an obstetric examination at the Provincial Hospital, including an ultrasound. Today, I had a 3D ultrasound at the Provincial Hospital.

Doctor's answer:
Hello, B-ultrasound is a routine examination performed by hospitals on patients, and to date, there have been no reports of it causing harm to patients. It is one of the six major imaging diagnostic equipment in the medical field.Analyzing the principle of B-ultrasound, it involves the transmission of ultrasound, which does not produce ionizing radiation or electromagnetic radiation. It is a form of sound wave transmission, and such sound waves pose no harm to human tissues. However, this does not mean that B-ultrasound scans can be performed freely throughout the entire pregnancy without time or frequency restrictions.
Experts point out that the number of B-ultrasound scans needed during pregnancy depends on specific circumstances. Under normal conditions, expectant mothers should have about three B-ultrasound scans during pregnancy, not exceeding five.
