New PET validation strategy optimizes Alzheimer's research spending

Researchers have developed a new validation strategy for scarce confirmatory PET measurements in Alzheimer disease studies, focusing on target-aligned validation rather than generic uncertainty sampling. The study, using the A4/LEARN PET archive, found that simple APOE4-balanced validation recovers most of the target-specific gain for APOE4 carrier status, achieving a confidence-interval width ratio of 0.923 at a PET budget of 200. Target-specific scoring showed greater benefits for age-slope analysis and cutoff-indexed PET positivity, suggesting that scarce protocol measurements should be allocated based on the specific claim being validated.
