What is an Internal Growth Scan?
The idea of a scan that measures your baby’s growth can feel daunting, especially for first-time moms. You may wonder: Will it hurt? Is it safe? What will it reveal? These questions are completely normal. The good news is that internal growth scans are safe, painless, and extremely valuable.
Understanding what to expect can ease a lot of that nervousness. Think of this scan as a progress report, one that ensures your baby is growing well and that your pregnancy is moving in the right direction.
How Is It Different from a Regular Ultrasound?
An
internal growth scan is a type of detailed ultrasound, but it differs in focus. While early ultrasounds confirm the pregnancy and anatomy scans assess organ structure, growth scans measure how well the baby is developing over time.
The growth scan typically involves the same external abdominal probe used in regular scans. In some cases, especially in the early second trimester or for specific measurements, a transvaginal probe may be used, but this is less common after 28 weeks.
Is It Painful or Risky?
Not at all! Internal growth scans are completely non-invasive and safe for both mother and baby. The sonographer applies a warm gel to your belly and uses the ultrasound probe to capture images. Some gentle pressure may be applied to get better visuals, but it should not be painful. If you experience discomfort, always let your provider know.
Step-by-Step Walkthrough of the Scan
- Preparation: No fasting or special prep is required. A moderately full bladder may be requested.
- Positioning: You’ll lie on your back, slightly propped up.
- Gel Application: A warm, water-based gel is applied to the abdomen.
- Ultrasound Imaging: The probe moves across your belly to capture fetal measurements, check fluid levels, and assess blood flow.
- Image Review: The sonographer or fetal specialist may explain the findings during or after the scan.
The whole process typically takes
20 to 40 minutes depending on fetal position and visibility.
What the Results Might Reveal
- Is your baby’s growth on track for gestational age?
- Are amniotic fluid levels normal?
- Is the placenta functioning optimally?
- Is blood flow through the umbilical cord within safe limits?
The scan may also provide early clues about potential complications. In most cases, results will be reassuring. If anything concerning is found, your doctor will recommend additional tests or monitoring.
Can You See Your Baby?
Yes, especially in the third trimester when the baby is more developed. You might see defined features, body movements, and even facial expressions. While internal growth scans are more clinical than emotional, many parents cherish the images and videos they receive.
What If The Baby Isn’t in a Good Position?
Sometimes, the baby’s position makes it hard to capture clear images. You may be asked to change positions, walk around briefly, or return for a repeat scan. This is perfectly normal and not a cause for concern.
