Notes on Creating a Standardized Version of DVARS

TL;DR

This paper proposes a method to standardize DVARS by constructing a sampling distribution, aiming to improve comparability of DVARS across different scanners and datasets.

Contribution

It introduces a standardized DVARS method based on sampling distribution construction to enhance cross-dataset consistency.

Findings

Standardized DVARS reduces variability across scanners.

Improved comparability of DVARS metrics.

Potential for more reliable fMRI data quality assessment.

Abstract

By constructing a sampling distribution for DVARS we can create a standardized version of DVARS that should be more similar across scanners and datasets.
