Dear experts,

I am currently working on a project that requires healthy brain MRI data, specifically in the FLAIR modality. I have downloaded the OASIS-3 dataset, and I am referencing the list of cognitively healthy subjects from the "CDR_cognitively_healthy.csv" file.

However, upon visually inspecting some of these MRI scans, I have noticed what appear to be abnormalities in a few cases. I would greatly appreciate any advice or insights from the community regarding this observation.

Thank you in advance for your help.

Best regards,

Parisa Zarei
