This examination is usually conducted between weeks 14 to 16 of pregnancy.
The functional development of many organs continues throughout the entire pregnancy and even after childbirth. However, for most organs, their physical structure is already in place at this stage of pregnancy. The examination enables the identification and diagnosis of structural abnormalities in the fetus, even in the early stages of pregnancy.
The examination includes a scan of the body systems such as the skull, brain parts, facial features, chest, heart, and lungs, abdominal organs, kidneys, intestines, sex organs, hands, and legs. Additionally, measurements are taken of the fetal head, abdomen, and hip bone, and are compared to the gestational age. The examination also checks the amount of amniotic fluid, the condition and position of the placenta, and the structure of the mother's uterus.
The examination is typically performed using a transvaginal approach (through the cervix) and sometimes via an abdominal approach, administered by specialized medical professionals.
The advantages of this examination include the ability to perform a transvaginal ultrasound, which provides a clearer view of fetal organs. Furthermore, during the early stages of pregnancy when the examination is conducted, any anomalies can be identified clearly, and if necessary, early termination of pregnancy can be considered.
