What Is an Anomaly Scan and Why Is It Essential?
An anomaly scan — also known as the mid-pregnancy scan or TIFFA scan — is a detailed ultrasound examination typically performed between 18 and 22 weeks of pregnancy. It is one of the most important scans during pregnancy, designed to carefully assess the development and structure of your baby. This scan goes well beyond a routine check, providing a thorough look at nearly every aspect of fetal growth and anatomy.
Why Is an Anomaly Scan Important?
The anomaly scan serves several vital purposes during your pregnancy journey. It provides a comprehensive picture of your baby's wellbeing and flags any concerns early enough to allow thoughtful decision-making. Key reasons it matters include:
- Detecting Physical Abnormalities: The scan examines the major organs — including the heart, brain, spine, kidneys, and limbs — to identify any structural differences that may require further investigation or specialist management.
- Assessing Growth: Your baby's measurements are carefully reviewed to confirm that growth is on track and in line with your stage of pregnancy.
- Placenta and Amniotic Fluid: The position of the placenta and the volume of amniotic fluid are assessed, as both play a critical role in the health of the pregnancy.
- Multiple Pregnancies: For those carrying twins or more, the scan also checks how each baby is growing and whether they are sharing a placenta — important information for ongoing care.
What to Expect During the Scan?
During your anomaly scan, a sonographer will use an ultrasound probe gently placed on your abdomen to produce images of your baby. The procedure is entirely painless and typically takes between 20 and 30 minutes, though this can vary depending on your baby's position. You may be asked to arrive with a comfortably full bladder, as this helps improve the quality of the images obtained.
Preparing for Your Anomaly Scan
A little preparation before your appointment can help ensure the scan goes as smoothly as possible:
- Stay Hydrated: Drinking water before your scan helps maintain amniotic fluid levels and can improve image clarity. Arrive with a moderately full bladder as advised by your care team.
- Wear Comfortable Clothing: Loose, comfortable clothing that allows easy access to your abdomen will make the appointment more comfortable for you.
- Bring Your Medical History: Carry any previous scan reports, blood test results, or medical records with you. This background information helps your specialist review your results in full context.
The anomaly scan is a vital part of prenatal care, offering reassurance and important information at a critical stage of your pregnancy. At Fetocare, every scan is performed with the thoroughness and time it deserves — and every finding is discussed with you openly before you leave.
