I think the ability to check the placenta and amniotic fluid levels is one of the most underrated benefits of this scan! It’s not just about the baby’s body; it’s about the whole environment. Great article.
Very helpful clarification on the routine scan vs. the anomaly scan. Glad to hear both are generally safe.
This is great info. Does the anatomy scan give a clear indication if the baby has a chance of having autism, or is it only for structural/physical abnormalities like spina bifida?
I had my routine fetal anatomy ultrasound at 20 weeks, and it was amazing to see how much detail the scan provided of my baby’s organs and overall development. The technician explained everything clearly, and it really gave me peace of mind about my baby’s health.
if something unusual is detected during the routine fetal anatomy scan, how soon would additional testing or follow-up scans be recommended?
