Area of Science:

  • Neuroimaging
  • Biomedical Engineering
  • Data Science

Background:

  • Automated processing pipelines are crucial for large-scale brain diffusion tensor imaging (DTI) studies.
  • Quality control (QC) and artifact removal are essential pre-processing steps for accurate diffusion parameter calculation.
  • Existing ENIGMA-compliant frameworks require robust methods for handling multi-site DTI data.

Purpose of the Study:

  • To design and compare three automated DTI processing pipelines for large cohort studies.
  • To evaluate the performance of different QC procedures, including RESTORE and DTIPrep, with simulated and real-world data.
  • To identify the most robust pipeline for analyzing multi-site brain DTI data from the Ontario Neurodegenerative Disease Research Initiative (ONDRI).

Main Methods:

  • Three automated DTI processing pipelines were developed by combining image processing software tools within the ENIGMA framework.
  • Simulated DTI datasets with controlled artifacts (eddy currents, motion, noise) and real VCI patient data were used for evaluation.
  • Performance was assessed using normalized differences from ground truth for simulated data and variability in diffusion parameters (FA, MD, AD, RD) for real data.

Main Results:

  • All pipelines demonstrated similar performance, especially for fractional anisotropy (FA) measurements.
  • The RESTORE algorithm-based pipeline showed the highest accuracy on artifact-containing DTI datasets.
  • A pipeline combining DTIPrep and RESTORE yielded the lowest standard deviation in FA measurements in normal-appearing white matter across subjects.

Conclusions:

  • The combined DTIPrep and RESTORE pipeline is the most robust for automated analysis of multi-site brain DTI data.
  • This pipeline provides reliable quality control and artifact removal, essential for large cohort studies.
  • The findings support the preference for this integrated pipeline in neuroimaging research involving DTI data.
