Usually scans for this type of detection are done around 18 to 23 weeks of gestational age called the ” anatomy scan “, “anomaly scan,” or “level 2 ultrasound”. Some resources indicate that there are clear reasons for this and that such scans are also clearly beneficial because ultrasound enables clear clinical advantages for assessing the developing fetus in terms of morphology, bone shape, skeletal features, fetal heart function, volume evaluation, fetal lung maturity,  and general fetus well being.
