TL;DR
High-resolution dhPET revealed significantly higher SUVRs in Aβ⁺ compared with Aβ⁻ subjects in supratentorial structures, including cerebral white matter, and in cerebellar gray matter.
Deep learning–based amyloid PET segmentation enables accurate MRI-free quantification of gray and white matter SUVRs and simplifies clinical workflow while maintaining diagnostic performance comparable to MRI-based methods for AD diagnosis.

The biodistribution of 18F-flortaucipir whole-body biodistribution for Japanese individuals was consistent with that of non-Japanese individuals, and Japanese readers showed high concordance with US readers on the interpretation of 18F-flortaucipir PET images to distinguish between AD and non-AD patterns.

A double-cutoff analysis suggest that scans in the 11 to 26 Centiloid range should be interpreted with caution depending on the context of use, and positivity cutoffs converged around 18 Centiloids (data-driven) and 27 Centiloids (visual reads).

While neither ASL nor DSC is fully comparable to 15O-H2O PET in all tumors, ASL presents a viable non-invasive alternative to DSC for glioma imaging and the findings encourage future studies to investigate the extent to which the combination of ASL and DSC can measure complementary tumor hemodynamics.

Widespread RFS predominates during early stages, whereas structural atrophy gradually becomes the dominant imaging feature as the disease advances, underscoring the potential of multimodal imaging biomarkers for the early diagnosis of IPD.

Cortical gray matter provides the most stable reference region and supports harmonized, covariate-adjusted normative datasets for clinical and research applications and is the major sources of variance in brain [¹⁸F]FDG-PET quantification in CN subjects.
