All you need to know about Scanning in Pregnancy

Pregnancy scanning, also known as prenatal ultrasound or prenatal imaging, refers to the use of ultrasound technology to create images of a developing fetus during pregnancy. These scans are an essential part of prenatal care, as they provide valuable information about the health and development of the baby and the progress of the pregnancy. Here are some common types of pregnancy scans:

Early Pregnancy Scan: This scan is performed during the first trimester, this scan confirms the pregnancy, determines the gestational age, and checks for the presence of multiple embryos. It can also identify potential issues like ectopic pregnancies or miscarriages.

Nuchal Translucency Scan: This scan is typically performed between 11 and 14 weeks of pregnancy. It assesses the thickness of the nuchal fold (a fold of skin at the back of the baby’s neck). Abnormal thickness may be associated with certain chromosomal abnormalities.

Anatomy Scan (or Level 2 Ultrasound): This detailed scan is usually performed around 18 to 22 weeks of pregnancy. It provides a comprehensive look at the baby’s anatomy, checking for the presence of all major organs and limbs. It can also reveal the baby’s sex if desired.

Doppler Ultrasound: Doppler ultrasound measures the blood flow through the umbilical cord and major blood vessels in the baby. It helps assess the baby’s well-being and can be used to monitor pregnancies with certain complications, such as preeclampsia.

Growth Scan: Growth scans may be performed at various points in the pregnancy to assess the baby’s size and growth. These scans are often used if there are concerns about fetal growth or if the pregnancy is considered high-risk.

Position and Presentation Scan: In the third trimester, a scan may be performed to check the baby’s position in the uterus and determine whether the baby is in a head-down (vertex) or breech position. This information is crucial for planning delivery, especially if a cesarean section is being considered.

Biophysical Profile (BPP): This test assesses the baby’s overall well-being and involves a combination of ultrasound measurements, including fetal movement, breathing, muscle tone, and amniotic fluid levels.

3D/4D Ultrasound: While not typically used for medical diagnosis, 3D and 4D ultrasounds provide three-dimensional and real-time images of the baby, allowing for a more detailed and lifelike view. They are often used for bonding and to capture images for keepsake purposes.

These scans play a crucial role in monitoring the health of both the mother and the developing fetus throughout pregnancy. It’s important to understand, ultrasound scans are generally considered safe, and should only be performed by qualified healthcare professionals when medically required. The frequency and timing of scans can vary depending on the individual pregnancy and any specific medical concerns. Healthcare providers will recommend the appropriate scans based on the woman’s medical history, risk factors, and the progress of the pregnancy.
