Typically Developing Participants from Late Childhood to Adolescence

This dataset provides diffusion-weighted MRI and structural T1-weighted MRI from typically developing participants spanning late childhood to adolescence. It is intended to support studies of white matter maturation and normative neurodevelopment.

The diffusion data were processed using ExploreDTI, while the structural T1-weighted images are provided in unprocessed form.

Dataset Overview

Modalities

  • Diffusion-weighted imaging (DWI)
  • T1-weighted structural MRI

Cohort

  • Typically developing participants
  • Age range: late childhood to adolescence

Data Contents

The dataset includes:

  • DWI volumes for each subject
  • Corresponding bval and bvec files
  • T1-weighted structural images for each subject

Processing status

  • Diffusion data: processed via ExploreDTI
  • T1-weighted data: unprocessed

This combination makes the dataset useful both for downstream diffusion analysis and for custom structural preprocessing workflows.

Related Dataset

The subjects in this release are the same as those in the related dataset:

This makes it possible to combine conventional diffusion analyses with neurite-orientation-based measures from the companion release.

Scientific Use

This dataset is suitable for:

  • White matter development studies
  • Adolescent brain maturation analyses
  • DTI and tractography method development
  • Comparison of diffusion-derived measures across development
  • Validation against NODDI-based developmental findings
  • Teaching and benchmarking for pediatric/adolescent diffusion MRI pipelines
