CCB Automated Tissue Extraction and Volume Calculation Workflow

Overview - Automated Tissue Extraction and Volume Calculation Workflow

This workflow takes raw un-skull-stripped volumes and generates tables of the total, GM, WM and CSF volumes.

Problem addressed by this workflow

Computing and tabulating the total Brain Volume (TBV), Gray-matter (GM), White-matter (WM) and CSF volumes for a collection of subjects.

Detailed Workflow Usage & Specifications

  • Any volumetric file format can be used for the raw unskull-stripped imput images (e.g., DICOM, DIrectories, Analyze, MNC, Nifti, etc.)
  • Image conversion to Analyze
  • Skull-stripping
  • Intensity Inhomogeneity correction
  • Volume Tissue Classification
  • Compute the Total, GM, WM and CSF brain volumes
  • Tabulate the Volumetric data for all tissue types and across subjects
  • Export the final volumetric table.

Pipeline Workflows

Footnotes

  • Outputs and results: tabular results are Nx4 matrices, where N=#-subjects and 4 are the 4 tissue types
  • Expected times: about 30 minutes.
  • Limitations: For some data/populations, the pre-processing steps (skull-stripping, tissue segmentation, etc.) may need to be improved/replaced by analogous processes (e.g., SSMA for Skull-stripping).
