Direct guidance
What to know or do
Ask which measurements matter, how they compare with earlier scans, the uncertainty around the estimate and whether repeat imaging or monitoring is planned.
What changes the answer
- Whether this is screening, diagnosis, monitoring, treatment or birth planning
- Pregnancy week, previous results and what the result could change
- Benefits, limits, alternatives, follow-up and the time available to decide

When to get individual help
Check the exact item or situation with a doctor, midwife, pharmacist or relevant clinician; the name of a broad category is not enough for a personal decision.
