This study examines the relationship between amyloid-PET signals in white matter and microstructural changes like free water and fiber integrity, finding that free water and WMH volume are more closely linked to Aβ-PET in WMH regions.

The paper examines how cortical morphology correlates with long-term placebo responses in multiple sclerosis patients, finding that non-responders have a more small-world-like cortical topology and lesion load inversely predicts cortical thickness in specific brain regions.

This paper develops personalized neural networks to detect transient neurotransmitter responses in PET images, showing improved sensitivity over traditional statistical methods.
