What is Morphological Screening?
Morphological screening, also known as a fetal anomaly scan or a mid-pregnancy ultrasound scan, is a detailed ultrasound examination performed to assess the baby’s structural development and identify any potential abnormalities. It is usually conducted between 18 to 22 weeks of pregnancy when the baby’s organs and body systems are significantly formed and visible.
Why is Morphological Screening Important?
The goal of morphological screening is to detect any structural abnormalities or conditions that may affect the health and well-being of the baby. Early detection allows for necessary medical interventions, management plans, or support to be put in place to ensure the best possible outcome for both the baby and the parents.
What Happens During the Morphological Screening?
During the morphological screening, a trained sonographer will perform an ultrasound examination. The sonographer will apply gel to your abdomen and use a device called a transducer to transmit sound waves into your womb. These sound waves will bounce back and create images of the baby’s internal structures, which the sonographer will interpret.
The sonographer will systematically examine different areas of the baby’s body, including the head, face, brain, spine, heart, stomach, kidneys, limbs, and placenta. They will measure certain structures and assess for the presence of any potential abnormalities.
What Can Morphological Screening Detect?
Morphological screening can detect various structural abnormalities, including but not limited to:
- Neural tube defects
- Cleft lip and palate
- Heart defects
- Abnormalities in the brain or spine
- Urinary tract abnormalities
- Abdominal wall defects
It’s important to note that not all conditions can be detected through morphological screening, and the scan is not a guarantee of a healthy baby.
Are There Any Risks or Discomfort Associated with Morphological Screening?
Morphological screening through ultrasound is non-invasive and generally safe for both the mother and the baby. It does not use any radiation. The gel applied on the abdomen may feel a bit cold initially, but overall, the procedure is painless and well-tolerated by most women.
Understanding when and why morphological screening is done can help expecting parents better prepare for this important scan. Through this ultrasound examination, potential structural abnormalities can be detected, allowing for early interventions and appropriate support during the pregnancy journey. Remember, it is always essential to consult with your healthcare provider for personalized information and guidance regarding your specific situation.
