How ultrasound works
High-frequency sound imaging—no ionizing radiation like CT.
Safety
When performed by trained staff for clinical indications, ultrasound is considered safe. Avoid unnecessary prolonged “keepsake” sessions.
Typical schedule
- Dating and fetal heart confirmation.
- Anatomy screening (timing per local protocol).
- Growth, placenta, fluid checks when indicated.
Bottom line
Trust your obstetric plan; do not self-order excessive scans from anxiety.
