Description

Two radioactive tracers both light up Alzheimer's tau tangles, and Bruna Bellaver and seventeen co-authors raced them head-to-head in a 2025 study of 132 people across the disease spectrum. Every participant received both scans, plus an amyloid scan to stage them.

Voxel-by-voxel accuracy maps showed the older tracer, flortaucipir, scoring numerically higher and wider than MK6240 at separating amyloid-positive from amyloid-negative healthy adults. The gap widened in mid-stage Braak regions, areas not expected to hold tau yet in such adults, which cuts both ways: sensitivity there may be signal or spillover. Groups ranged from healthy controls to dementia patients. The authors offer the maps as a chooser's guide: the tracers are not interchangeable, and which one wins depends on the stage and the question being asked.
