The pregnancy process is a period that must be carefully monitored by both expectant mothers and doctors. Various screenings are performed at specific weeks to ensure that the baby's development is progressing healthily. One of the most important of these screenings is the detailed fetal anatomy scan, commonly known as a detailed ultrasound. So, what is a detailed ultrasound, why is it performed, and when is the best time for it? Here are all the details you need to know…
What is a Detailed Ultrasound?
A detailed ultrasound is a special ultrasound examination in which the baby’s organs are thoroughly examined and the development process is evaluated. This screening checks whether the baby has any developmental anomalies. The brain structure, spinal development, heart, internal organs, facial structure, hands, and feet are all examined in detail.
A detailed ultrasound is also referred to as a level 2 ultrasound and is performed using high-resolution ultrasound devices.
When is a Detailed Ultrasound Performed During Pregnancy?
A detailed ultrasound is typically performed between the 18th and 23rd weeks of pregnancy. However, the ideal time frame is between the 20th and 22nd weeks. This is because the baby's organs have developed sufficiently during these weeks, allowing for a more detailed assessment.
In some cases, your doctor may recommend an additional detailed ultrasound at an earlier or later stage. If there are genetic risks, anomalies in previous pregnancies, or risks detected in certain screening tests, an earlier detailed examination may be required.
Importance of a Detailed Ultrasound
A detailed ultrasound is essential for closely monitoring the baby’s development. This screening helps:
- Detect the baby’s organ development and structural anomalies.
- Identify conditions such as heart diseases, brain development issues, and facial anomalies like cleft palate at an early stage.
- Assess the umbilical cord and placenta to evaluate the baby’s nutrition in the womb.
- Investigate potential signs of genetic disorders.
Detecting any anomalies early is crucial for ensuring appropriate medical interventions and planning for the baby's health after birth.
How is a Detailed Ultrasound Performed?
A detailed ultrasound is performed similarly to other ultrasound examinations, using a probe and applying gel to the abdominal area. The expectant mother does not need to be in a fasting state. The procedure typically lasts between 30 to 45 minutes, and if the baby is in a favorable position, all necessary measurements can be taken smoothly.
In some cases, if the baby’s position does not allow for clear imaging, the doctor may ask the expectant mother to walk for a short time, change positions, or wait for a while to complete the measurements.
What Do Detailed Ultrasound Results Indicate?
After a detailed ultrasound, your doctor will evaluate the images and provide information about your baby's development. In most cases, expectant mothers are reassured by the confirmation that their baby is developing normally. However, in some cases, the doctor may request additional tests or refer the mother to a perinatology specialist for further evaluation.
If any abnormalities are detected, the doctor will provide guidance on suitable treatment options and postnatal care planning.
A detailed ultrasound is one of the most important screenings during pregnancy and is typically performed between the 18th and 23rd weeks. This examination provides critical information about the baby’s organ development, structural anomalies, and overall health status. Regular doctor check-ups are essential for closely monitoring your baby's healthy development.
