Brain abnormalities detected at a 20-week scan are relatively rare, but critical for early intervention. While most pregnancies will not show any brain abnormalities at this stage, it's important for expecting parents to remember that this scan serves as a vital checkpoint for detecting a range of potential issues. Early identification allows for proper planning and, in some cases, interventions that can significantly impact the baby's health post-birth. Nonetheless, the majority of scans reveal no abnormalities, offering reassurance to parents during the midpoint of pregnancy.
