MRI preprocessing levels impact brain foundation model performance

A new study on arXiv explores the impact of MRI preprocessing on the performance of brain MRI foundation models. Researchers found that increasing preprocessing levels does not consistently improve model utility, with lower levels like P2 often being the most cost-effective. While some specific downstream tasks benefit from more intensive preprocessing, much of this advantage can be recovered by applying stronger preprocessing during the transfer learning phase, suggesting a more targeted approach to MRI data preparation. AI

IMPACT Suggests optimizing MRI preprocessing for foundation models can improve cost-efficiency without sacrificing performance.
