Staging β-Amyloid Pathology With Amyloid Positron Emission Tomography.

JAMA Neurology, 2019
Importance Different brain regions appear to be involved during β-amyloid (Aβ) accumulation in Alzheimer disease (AD), but a longitudinally valid system to track Aβ stages in vivo using positron emission tomography (PET) is lacking.

Quantum Tomography twenty years later [PDF]

Phys. Scripta, 90, 074031 (17 pp) (2015), 2015
A sample of some relevant developments that have taken place during the last twenty years in classical and quantum tomography are displayed. We will present a general conceptual framework that provides a simple unifying mathematical picture for all of them and, as an effective use of it, three subjects have been chosen that offer a wide panorama of the

Tau Positron‐Emission Tomography in Former National Football League Players

New England Journal of Medicine, 2019
BACKGROUND Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease that has been associated with a history of repetitive head impacts. The neuropathological diagnosis is based on a specific pattern of tau deposition with minimal amyloid ...
