Dataset validation toolkit for neurology brain imaging (NIfTI)

NeuroTK: Dataset Validation for Neurology Brain Imaging

Motivation

Neurology brain imaging datasets are heterogeneous and frequently contain inconsistencies. Geometry, spacing, orientation, and annotation issues occur commonly across CT and MRI collections. These problems often surface late in modeling, when remediation is costly and compromises reproducibility. NeuroTK surfaces issues early, explicitly, and reproducibly to support dataset hygiene prior to analysis.

Scope

NeuroTK focuses on dataset quality assurance prior to downstream analysis. It provides dataset-level and file-level validation with structural and geometric consistency checks, and assessment of annotation presence and integrity.

• Dataset-level and file-level validation
• Structural and geometric consistency checks
• Annotation presence and integrity assessment

NeuroTK does not modify scientific data.

Installation

pip install neurotk

Quickstart

neurotk validate --images imagesTr --labels labelsTr --out report.json

Inputs are expected as flat directories of NIfTI files, and filenames must match exactly for image–label pairing.

dataset/
  imagesTr/
    case_001.nii.gz
    case_002.nii.gz
  labelsTr/
    case_001.nii.gz
    case_002.nii.gz

Output

NeuroTK emits a JSON report containing a dataset-level summary, per-file diagnostics, and explicit listings of detected issues.

{
  "summary": {"num_images": 100, "files_with_issues": 7},
  "files": {"case_001.nii.gz": {"issues": ["label_missing"]}}
}
