    Why is the Second Trimester Anomaly Scan Important During Pregnancy?

    Updated on 3 November 2023

    What is the purpose of the anomaly scan during pregnancy?

    Several parts of the baby's body are examined in depth during the Second Trimester Anomaly Scan screening. It gives the sonographer the ability to scan for 11 uncommon conditions. These problems are the only ones the scan is looking for, and it can't identify everything wrong.

    At the second-trimester anomaly scan, what happens?

    Sonographers are the medical professionals who perform most fetal anomaly scans. So that the sonographer can get clear pictures of the infant, scans are performed in a dimly lighted environment. You'll be asked to recline on a sofa and expose your abdomen by removing your skirt or pants to your hips and lifting your top to your chest. To protect your clothes from the gel placed on your stomach, a sonographer or their helper will wrap tissue paper over it.

    Next, the sonographer will use a portable probe to inspect the baby's internal organs to report an anomaly scan. It's the gel's work to keep the probe in contact with your skin. The ultrasound screen will display a black-and-white picture of the infant. Scanners do not use any force while doing the fetal anomaly scan. However, the finest images of the infant may need some pressure from the sonographer. Thus, this may be a little awkward.

    They must maintain the screen to allow them to see the infant. The screen may be in front of them, or it may be at an angle to their side. While the sonographer is scanning your baby, they may need to be silent to focus on what they are doing. Once the check is complete, they will be able to chat with you about the images. The anomaly scan time duration session typically takes 30 minutes or less.

    It might be challenging to capture a decent image if the baby is resting in an odd posture or moving around a lot, or if you are above average weight or your body tissue is thick. It does not imply any cause for alarm. For your appointment, you may require a full bladder. Before you arrive, your doctor or midwife will tell you what to expect. If you're still unsure, you may always reach out to them and inquire.

    Can I find out the gender of my child?

    You should ask the sonographer at the beginning of the test in pregnancy whether you wish to know the sex of your baby.

    It is now prohibited in most areas to be told the sex of a baby by a hospital. Some hospitals may refuse to inform you. Please find out more details from your sonographer or midwife by contacting them.

    My buddy or partner would want to accompany me to the scan.

    Yes. Screening at anomaly scan analyses if the baby has a health issue, which may be a shock, so a companion can help you deal with it. A friend or family member may be able to accompany you to the appointment.

    Due to a lack of childcare options, most hospitals do not allow children to participate in scans. Before your visit, make sure to inquire about this with the hospital.

    Is the scan safe for my unborn child and me?

    An ultrasound scan has no known dangers to you or your unborn child. Still, it's vital to weigh the benefits and drawbacks before deciding.

    You may be forced to make important choices based on the information. Further tests that carry a risk of miscarriage may be given to you, and you will have to decide whether or not to have them performed.

    Is this scan a necessity?

    No, it's up to you whether or not you want it. Some parents are eager to learn whether their child has a medical problem, while others are not so eager.

    Pregnancy care will continue as usual if you decline the scan.

    When can I expect to get the scan's results?

    At the time of the scan, the ultrasound technician will be able to provide you with the report details of a test anomaly scan.

    Between 18 and 21 weeks into your pregnancy, you'll likely get a comprehensive ultrasound scan called the mid-pregnancy or anomaly scan.

    Pregnant women are encouraged to take advantage of the 20-week screening scan, but they are not obligated to. The scan examines your baby's physical growth, but it cannot detect every ailment.

    The procedure for the 20-week screening scan is the same as that for the 12-week screening. In black and white, it depicts the newborn from the side. No 3D or color visuals are used in the screening procedure.
