Description

Maxime Descoteaux leads a team of eight authors in 2025 in arguing that brain scan data from many hospitals must be harmonized before anyone builds norms from it. Diffusion MRI measures of white matter vary by site and scanner brand, biasing any pooled numbers.

The study works with the ADNI Alzheimer's cohort, taking twenty-one sites with at least ten participants each. It tests whether the standard harmonization method, ComBat, truly removes site bias for tract measurements, something not convincingly shown in this cohort before. Without that step, a patient could look abnormal merely for being scanned at the wrong hospital.
