Modern 3D ultrasound images provide greater detail for prenatal diagnosis than the older 2D ultrasound technology. [6] While 3D is popular with parents desiring a prenatal photograph as a keepsake, [7] both 2D and 3D are discouraged by the FDA for non-medical use, [8] but there are no definitive studies linking ultrasound to any adverse medical ...
The final stage is the fetal stage which begins at the ninth week of pregnancy and lasts until birth. Another way to measure pregnancy is by trimesters. The first trimester is from conception to 12 weeks of pregnancy, the second trimester is from 13 to 28 weeks of pregnancy, and the third trimester is from 29 weeks until birth.

Social emotional development represents a specific domain of child development. It is a gradual, integrative process through which children acquire the capacity to understand, experience, express, and manage emotions and to develop meaningful relationships with others. [ 1 ]
3D ultrasound is a medical ultrasound technique, often used in fetal, cardiac, trans-rectal and intra-vascular applications. 3D ultrasound refers specifically to the volume rendering of ultrasound data. When involving a series of 3D volumes collected over time, it can also be referred to as 4D ultrasound (three spatial dimensions plus one time ...
Fetal movements at the end of first trimester (early fetal stage) detected by 3D ultrasound. The parts of the fetal brain that control movement will not fully form until late in the second trimester, and the first part of the third trimester. [7]
Quickening indicates the start of fetal movements, usually felt 14–26 weeks after conception, or between the fourth and sixth month. [5] [6] A woman pregnant for the first time (i.e., a primigravida woman) typically feels fetal movements at about 20–21 weeks, whereas a woman who has given birth at least once will typically feel movements ...
Prior to 18 weeks' gestation, the fetal organs may be of insufficient size and development to allow for ultrasound evaluation. Scans performed beyond 22 weeks' gestation may limit the ability to seek pregnancy termination, depending on local legislation. [1] Two-dimensional (2D) is used to evaluate fetal structures, placenta, and amniotic fluid ...
