The intent of this research protocol is to test the equivalency of two amyloid imaging drugs (C11 Pittsburgh Compound B and F18 Flutemetamol). The investigators hypothesize that there will be no significant difference in the distribution of the agents to areas of amyloid deposition in the brain or to other normal brain structures. Recent data have shown similarity in the distribution of the drugs in subjects with AD or mild cognitive impairment (MCI). No comparison data of the two PET drugs in normal subjects has been published. It is important to understand differences in the images and biodistribution from the ...

Rheumatoid arthritis (RA) patients have a higher prevalence of subclinical atherosclerosis than the general population. In addition, they experience higher rates of heart failure with preserved ejection fraction (HFpEF). There is evidence that myocardial mechanics and left ventricular diastolic function are more abnormal in the RA population and these changes occur earlier than in the general population. Recently a study suggested that RA patient have abnormal myocardial inflammation during a disease flare and that this is improved with anti-inflammatory treatment. Our study is aimed at describing the prevalence of myocardial inflammation in patients during active RA disease flares and comparing ...

A brain PET scan is recognized as "reasonable and necessary" for some patients with "a recently established diagnosis of dementia" (Centers for Medicare and Medicaid Services, Decision Memo CAG-00088R, 2004), but evidence is less clear for patients having less severe cognitive problems. A substantial portion of such patients will develop Alzheimer's disease and other forms of dementia, which affect millions of people in the U.S., costing us over $100 billion annually. This project employs a prospective randomized protocol to determine whether PET scanning can help distinguish those patients with early Alzheimer's changes in their brains from those having other causes ...

Since its launch in 2004, the overarching aim of the Alzheimer's Disease Neuroimaging Initiative (ADNI) has been realized in informing the design of therapeutic trials in AD. ADNI3 continues the previously funded ADNI-1, ADNI-GO, and ADNI-2 studies that have been combined public/private collaborations between academia and industry to determine the relationships between the clinical, cognitive, imaging, genetic and biochemical biomarker characteristics of the entire spectrum of Alzheimer's disease (AD). The overall goal of the study is to continue to discover, optimize, standardize, and validate clinical trial measures and biomarkers used in AD research.
