Embryology & Early Development
Gestation (gestational age)
Gestation is the period of development in the womb, and gestational age describes how far along a pregnancy is.
In short: Gestation (gestational age)
- Encephalocele forms very early in gestation.
- Gestational age guides the timing of imaging.
- It is measured in weeks of pregnancy.
- It helps plan diagnosis and care.
What it is
It is the period of development in the womb, with gestational age describing how far along a pregnancy is, measured in weeks. It is a key reference point for prenatal care.
Understanding Gestation (gestational age)
Because encephalocele forms in the first weeks of gestation, and because imaging like ultrasound and fetal MRI is timed to gestational age, this measure helps plan diagnosis. For example, an encephalocele may be seen on ultrasound as early as 11–13 weeks, while fetal MRI for detailed brain assessment is typically done later in pregnancy.
Why it matters
Understanding gestational age helps families follow the timing of prenatal tests and see why certain imaging is done at particular points in pregnancy.
