What your results can mean
Reading your report
Most scans are normal; if something unusual is seen, your doctor will explain what it means and whether more tests are needed.

The scan can show differences in how the baby's organs, spine, heart or limbs have formed, a low-lying placenta, or fluid concerns. Most scans are normal, and many findings are minor and need only follow-up.
Who usually has this test
All pregnant women around 18 to 22 weeks, including after IVF, and women with a higher chance on earlier screening.
Risks and aftercare
No radiation is used and it is considered safe for you and the baby; lying on your back for a while can be tiring, so tell staff if you feel unwell.
