Advances in fetal brain MRI allow prenatal diagnosis of challenging brain abnormalities. This review covers major malformations, lesions, and ventriculomegalies, detailing MRI sequence advantages.

Area of Science:

  • Radiology
  • Neuroimaging
  • Prenatal Diagnosis

Background:

  • Magnetic Resonance (MR) imaging and faster techniques have significantly advanced in-utero fetal brain imaging over the last decade.
  • Prenatal diagnosis of complex fetal brain abnormalities is now feasible through detailed analysis of morphology and signal characteristics.

Purpose of the Study:

  • To illustrate and discuss major fetal brain malformations and associated morphologic changes.
  • To review destructive lesions and isolated ventriculomegalies in the fetal brain.
  • To provide an overview of the advantages and disadvantages of T1 and T2 MR imaging sequences for fetal brain assessment.

Main Methods:

  • Review of neuroimaging literature focusing on in-utero fetal brain MR imaging.
  • Analysis of illustrative cases demonstrating normal brain development and various pathologies.

Related Experiment Videos

  • Discussion of T1 and T2 weighted imaging sequences and their utility.

    • Main Results:

    • Detailed illustration of normal fetal brain development as a baseline for comparison.
    • Comprehensive discussion of major brain malformations, including specific morphologic changes.
    • Categorization and description of destructive lesions and isolated ventriculomegalies.
    • Comparative analysis of T1 and T2 sequences for fetal brain imaging.

    Conclusions:

    • In-utero fetal brain MRI is a powerful tool for diagnosing complex brain abnormalities prenatally.
    • Understanding normal development and specific imaging features is crucial for accurate diagnosis.
    • Knowledge of sequence-specific advantages and limitations aids in optimizing fetal MR imaging protocols.
