When is a pregnancy ultrasound performed?
During pregnancy, ultrasound is performed several times — each stage has its own purpose. Choosing the right time makes it possible to assess the development of the fetus and to detect possible changes in a timely manner. The timing is determined individually by radiologist Lana Ezieshvili according to the features of your pregnancy.
The main ultrasound scans
- Early scan (6–8 weeks) — confirms an intrauterine pregnancy, the number of fetuses, the heartbeat and the exact term.
- First-trimester screening (11–13⁺⁶ weeks) — measurement of the nuchal translucency (NT) and assessment of the risk of chromosomal abnormalities.
- Anatomy scan (18–22 weeks) — a detailed assessment of the fetal organs and systems (Level II ultrasound).
- Third trimester (30–34 weeks) — fetal growth, weight, the placenta, amniotic fluid and blood flow.
Additional examinations
Depending on the indications, an additional ultrasound or Doppler scan may be ordered — for example, when fetal growth restriction is suspected, in a high-risk pregnancy or when the amount of amniotic fluid changes. In such cases Lana Ezieshvili sets up an individual monitoring schedule.
Why is the timing important?
Some examinations (such as the NT or anatomy scan) are only informative at a specific stage. Missing the window reduces the opportunity for early diagnosis, so it is important that the scans are done on time.
Conclusion
The timing of pregnancy ultrasound is clearly defined — each scan is an important stage in monitoring a healthy pregnancy. For the exact timing and a monitoring schedule, book a visit with radiologist Lana Ezieshvili.
