Dynamic PET Measures of Tau Accumulation in Cognitively Normal Older Adults and Alzheimer’s Disease Patients Measured Using [18F] THK-5351
BACKGROUND [18F]THK5351, a recently-developed positron emission tomography (PET) tracer for measuring tau neurofibrillary tangle accumulation, may help researchers examine aging, disease, and tau pathology in living human brains. We examined THK5351 tracer pharmacokinetics to define an optimal acquisition time for static late images. METHODS Primary measurements were calculation of regional v...
متن کاملLongitudinal Assessment of Tau Pathology in Patients with Alzheimer’s Disease Using [18F]THK-5117 Positron Emission Tomography
The formation of neurofibrillary tangles is believed to contribute to the neurodegeneration observed in Alzheimer's disease (AD). Postmortem studies have shown strong associations between the neurofibrillary pathology and both neuronal loss and the severity of cognitive impairment. However, the temporal changes in the neurofibrillary pathology and its association with the progression of the dis...
متن کاملComparison of New Tau PET-Tracer Candidates With [18F]T808 and [18F]T807
Early clinical results of two tau tracers, [(18)F]T808 and [(18)F]T807, have recently been reported. In the present study, the biodistribution, radiometabolite quantification, and competition-binding studies were performed in order to acquire comparative preclinical data as well as to establish the value of T808 and T807 as benchmark compounds for assessment of binding affinities of eight new/o...

s | 11 and path of small molecule. FITC-dextran (4kDa) was injected into cortices of young, aged, and AD mice. Centering the injection site, circle mask was divided into eight pieces, which were classified into artery or vein-dominant based on vessel distribution. We compare the intensity and decline rates of FITC signal at each piece of the mask. The discrepancy transforms into the uniformity ...
