Prognostic Accuracy of Fetal MRI in Predicting Postnatal Neurodevelopmental Outcome

Area of Science:

• Medical Imaging
• Neurology
• Developmental Pediatrics

Background:

• Fetal MR imaging (MRI) demonstrates high diagnostic accuracy for fetal brain abnormalities.
• Its ability to predict postnatal neurodevelopmental outcomes remains less understood.
• This study investigates the prognostic capability of fetal MRI.

Purpose of the Study:

• To determine the prognostic accuracy of fetal MR imaging in predicting postnatal neurodevelopmental outcomes.
• To assess the agreement between prenatal imaging diagnoses and postnatal outcomes.
• To evaluate the predictive value of prenatal prognosis on long-term neurodevelopment.

Main Methods:

• Retrospective analysis of 145 fetal MR images over a 10-year period.
• Prenatal prognosis categorized as favorable, indeterminate, or poor by a pediatric neurologist.
• Postnatal outcome assessed using Gross Motor Function Classification System and epilepsy development.

Main Results:

• High agreement (93.0%) between prenatal and postnatal imaging diagnoses.
• Favorable prognosis predicted in 44.2% of cases; indeterminate in 50.0%; poor in 5.8%.
• Excellent agreement (93.5%) between favorable prenatal prognosis and favorable postnatal outcome.

Conclusions:

• A favorable prenatal prognosis derived from fetal MR imaging is highly predictive of a favorable postnatal neurodevelopmental outcome.
• Further research is warranted to clarify the prognostic role of fetal MRI for indeterminate and poor risk pregnancies.
• Fetal MRI offers valuable insights into predicting neurodevelopmental trajectories.
