Pregnancy ultrasounds are an exciting part of your prenatal journey. This comprehensive guide explains everything you need to know about baby scans.
What is an Ultrasound?
An ultrasound is an imaging modality that sends sound waves into your body. These sound waves bounce back off your organs, creating real-time images on a screen.
What Can Ultrasounds Reveal?
Pregnancy ultrasounds can:
- Confirm pregnancy and check viability
- Monitor fetal development at each stage
- Detect potential complications like ectopic pregnancies
- Screen for chromosomal abnormalities
- Check placenta position and amniotic fluid levels
- Determine gender (usually from 16 weeks)
Types of Scans
Abdominal Ultrasound
The most common type, where a transducer is moved across your belly with gel.
Transvaginal Ultrasound
Used in early pregnancy for clearer images, involving a small probe inserted into the vagina.
The Typical Ultrasound Timeline
6-10 Weeks: Early Pregnancy Scan
- Confirms pregnancy location
- Detects heartbeat
- Establishes due date
11-14 Weeks: First Trimester Screening
- Nuchal translucency measurement
- Dating confirmation
- Early anatomy check
18-22 Weeks: Anomaly Scan
- Comprehensive anatomy assessment
- Checks all major organs
- Often when gender is confirmed
Third Trimester: Growth Scans
- Monitors baby's growth
- Checks position
- Assesses placenta and fluid levels
Advanced Scan Types
3D Ultrasound
Creates still three-dimensional images of your baby's features.
4D Ultrasound
Shows real-time 3D movement - like watching a live video.
Doppler Studies
Evaluates blood flow and oxygen delivery to your baby.
Biophysical Profile
Assesses fetal wellbeing through movement, breathing, and fluid levels.
Is Ultrasound Safe?
Ultrasound has been used safely in pregnancy for over 50 years. Unlike X-rays, ultrasound uses sound waves - not radiation. When used according to medical guidelines and at appropriate diagnostic levels, ultrasound imaging is considered a safe choice for pregnancy care.
