Does a brain ultrasound for a six-month-old baby have an impact on the baby?

Patient's question:

No

Doctor's answer:

Generally, 3-5 ultrasound scans are performed during pregnancy. In the early stages of pregnancy, one scan is done to confirm the pregnancy, estimate embryonic development, and diagnose common early pregnancy conditions such as ectopic pregnancy, molar pregnancy, and various types of miscarriage. In the second trimester, specifically between weeks 22-26, a 4D color Doppler ultrasound is conducted for structural anomaly screening to check for gross fetal abnormalities and major organ malformations. In the late stages of pregnancy, the focus is on assessing the fetus, amniotic fluid, and placental conditions.
