Area of Science:

  • Neuroimaging
  • Fetal Development
  • Medical Ultrasound

Background:

  • Fetal brain maturation involves complex cortical development, including sulcation.
  • Establishing normative data for sulcation patterns is crucial for assessing neurodevelopmental status.

Purpose of the Study:

  • To define normal fetal brain sulcation patterns and their chronological appearance using transabdominal ultrasound.
  • To compare ultrasound findings with established fetopathological and MRI references for brain maturation.

Main Methods:

  • Prospective analysis of 158 normal fetal brains (21-34 gestational weeks).
  • Standardized transabdominal ultrasound imaging in axial, coronal, and sagittal planes.
  • Evaluation across eleven distinct views.

Main Results:

  • Detailed sequential development of cerebral sulci described by gestational age.
  • Chronology correlated with anatomo-pathologic references (mean 1-week lag).
  • Consistency with MRI findings observed, without a significant lag.

Conclusions:

  • Provides accurate ultrasound landmarks for normal fetal brain sulcation.
  • Enhances understanding of fetal brain cortex maturation.
  • Offers valuable insights for diagnosing fetal brain diseases.
