| Details | Purpose of the Fetal Anomaly Scan:
Screening for Physical Conditions:
The scan screens for 11 different physical conditions, according to GOV.UK.
Detecting Structural Problems:
It aims to identify any structural abnormalities in the fetus that might require further investigation or specialized care after birth.
Informing Decision-Making:
The scan results can help parents make informed decisions about their pregnancy, including whether to continue the pregnancy or consider termination in cases of severe abnormalities.
Assessing Placenta and Amniotic Fluid:
The scan also assesses the placenta and amniotic fluid to ensure proper placement and volume.
What is Assessed During the Scan:
Brain and Face: The scan checks for proper development and any structural anomalies.
Spine and Limbs: The scan examines the spine and limbs for any alignment issues or abnormalities.
Heart and Chest: It evaluates the heart's structure and function, checking for any cardiac defects.
Abdominal Organs: The scan inspects the stomach, kidneys, and bladder for any problems.
Placenta and Amniotic Fluid: It ensures the placenta is properly positioned and the amniotic fluid volume is adequate.
Important Considerations:
Not a Perfect Test:
While the anomaly scan is very effective at detecting many conditions, it cannot detect all potential problems.
Experienced Hands:
Oxford Fetal Medicine says the scan is most effective when performed by experienced professionals.
Potential for "Soft Markers":
Sometimes, minor irregularities are found that may or may not indicate a problem. These are sometimes referred to as "soft markers" and may require further investigation according to Norfolk and Norwich University Hospitals NHS Foundation Trust.
Ethical Considerations:
Some reports recommend considering the implications of the scan results and potential impact on the decision to continue the pregnancy |
