MRI-Based Neurodevelopmental Risk Stratification in Infants With White Matter Injury

30 de septiembre de 2026 actualizado por: First Affiliated Hospital Xi'an Jiaotong University

Multicenter Study for Developing an MRI Assessment System for Neurodevelopmental Risk Stratification in Infants With White Matter Injury

The goal of this observational study is to develop and evaluate an MRI-based assessment system for predicting neurodevelopmental outcomes in infants with punctate white matter lesions (PWML). This is a multicenter, bidirectional cohort study that includes both a retrospective cohort identified from existing clinical and imaging databases and a prospective cohort of consecutively enrolled participants. The study aims to better understand how MRI findings are associated with later developmental outcomes and to identify imaging markers that may help stratify developmental risk.

The main questions it aims to answer are:

  1. Which MRI features are associated with adverse neurodevelopmental outcomes in infants with PWML?
  2. Can MRI-based quantitative assessment methods provide early risk stratification for neurodevelopmental outcomes in infants with PWML?

Participants with PWML diagnosed by brain MRI will be followed and evaluated for neurodevelopmental outcomes. Researchers will analyze clinical information and MRI findings collected from participants to develop and validate prediction models. Participants will:

  1. undergo brain MRI examinations according to clinical protocols;
  2. receive standardized neurodevelopmental assessments during follow-up;
  3. have their MRI findings and developmental outcomes analyzed to identify factors associated with later neurodevelopment.

Población de estudio

This study includes infants with punctate white matter lesions (PWML) diagnosed by conventional brain MRI. Eligible participants are infants born at a gestational age of ≥32 weeks and <42 weeks who underwent MRI examination at a corrected gestational age of ≤45 weeks. This multicenter observational cohort study includes retrospective and prospective participants. Clinical information, MRI findings, and longitudinal neurodevelopmental outcomes will be collected to investigate MRI-based assessment methods and predictors of adverse neurodevelopmental outcomes.

Periodo de tiempo
Adverse neurodevelopmental outcome at 2 Years
Periodo de tiempo: At 2 Years of Age

The percentage of participants with an adverse neurodevelopmental outcome at 2 years of age will be assessed using standardized developmental assessment tools, including the Bayley Scales of Infant and Toddler Development, Second or Fourth Edition (Bayley-II or Bayley-IV), Gesell Developmental Schedules, or the Children's Neuropsychological Development Scale, according to the assessment tool and version used at each participating center. Adverse neurodevelopmental outcome will be defined according to predefined criteria based on developmental assessment scores in the cognitive, motor, and language domains, when available. MRI-derived measures will be analyzed to characterize the extent and pattern of white matter injury and to evaluate their prognostic value for subsequent neurodevelopmental outcomes. These measures will include lesion burden, semiquantitative MRI metrics, DTI-based measures, and structural disconnection measures derived from multimodal MRI.
