This study used four-dimensional (4D) sonography to establish normal standards for fetal neurobehavioral development across all trimesters. Findings show quantifiable neurobehavioral development is possible, with specific movement and expression patterns evolving throughout gestation.

Area of Science:

  • Prenatal Medicine
  • Developmental Neuroscience
  • Medical Imaging

Background:

  • Fetal neurobehavioral development is crucial for long-term outcomes.
  • Establishing normative data for fetal neurodevelopment is essential for early detection of abnormalities.
  • Four-dimensional (4D) sonography offers advanced visualization capabilities for prenatal assessments.

Purpose of the Study:

  • To construct normal standards for fetal neurobehavioral development.
  • To utilize longitudinal observations across all trimesters via 4D sonography.
  • To create fetal neurological charts based on movement and expression patterns.

Main Methods:

  • 100 healthy singleton pregnancies were recruited for longitudinal 4D ultrasound examinations.
  • Fetal neurodevelopmental parameters were evaluated from 7 to 40 weeks' gestation.

  • Maternal and fetal characteristics, fetal movements, and facial expressions were recorded.

    • Main Results:

    • 7 parameters in the first trimester and 11 in the second/third correlated with gestational age (P<0.05).
    • Fetal movement frequency increased during the first trimester.
    • Facial expressions and movement patterns tended to decrease from the second to third trimesters.

    Conclusions:

    • 4D sonography enables quantitative assessment of normal fetal neurobehavioral development.
    • Further multicentric studies are needed to establish comprehensive normative data.
    • The predictive validity of fetal neurobehavior on child developmental outcomes requires further investigation.
