In addition to the standard scans, ultrasound can be used in later pregnancy for specific medical indications. These examinations are not routine but performed only when clinically relevant.
Placenta location is assessed if the placenta is positioned low in the uterus, close to or covering the internal cervical opening. A low-lying placenta (placenta previa) may influence planning for delivery, and is therefore monitored with ultrasound, often later in pregnancy.
Amniotic fluid volume can be estimated when there is a suspicion of too little fluid (oligohydramnios) or too much (polyhydramnios). The assessment is based on visual estimation rather than exact measurement.
In some cases, Doppler ultrasound is used to measure blood flow in the umbilical cord, uterine vessels or fetal vessels. It can provide information about placental function and whether fetal growth may be affected.
Towards the end of pregnancy, ultrasound can be used to confirm fetal position, such as head or breech presentation, when clinical examination does not give enough information. This is done only when necessary.
These ultrasound examinations are therefore targeted and performed only when there is a specific medical question.
Alma’s tips 🌿
• These ultrasounds are performed only when there is a clear medical indication.
• Each examination reflects conditions at the time it is performed.
• They complement, but do not replace, regular pregnancy follow-up.
