Area of Science:

  • Neuroscience
  • Medical Imaging

Background:

  • Multisite magnetic resonance imaging (MRI) studies offer significant potential for advancing neuroscience.
  • Scanner variability and non-standardized protocols can compromise the reliability and repeatability of MRI-derived brain measures.

Purpose of the Study:

  • To implement and evaluate a standardized MRI protocol across multiple sites and scanners.
  • To assess the impact of standardization on data quality and test-retest variability for multisite research.

Main Methods:

  • A standardized MRI protocol, based on the Adolescent Brain Cognition Development (ABCD) study, was implemented across two sites and four MRI scanners (Siemens, Philips, GE).
  • Data included anatomical scans (T1, T2 weighted), diffusion-weighted imaging (DWI), and resting-state functional MRI (rs-fMRI).
  • Standardized, containerized pipelines were used for data preprocessing, with evaluation of image quality metrics and test-retest variability.

Main Results:

  • Successful implementation of standardized MRI protocols was achieved with minor adjustments for scanner-specific technical variations (e.g., repetition time, b-values, DICOM export).
  • Containerized preprocessing pipelines demonstrated benefits for managing multisite data.
  • Evaluation of image quality metrics and test-retest variability provided insights into protocol performance across different scanners and sites.

Conclusions:

  • Standardized MRI protocols and containerized data processing are crucial for enhancing the reliability of multisite neuroscience studies.
  • Careful optimization of image acquisition parameters is necessary to mitigate scanner-induced variability.
  • This work offers practical guidance for implementing robust multisite neuroimaging research.
