"Improved methods of biomarker detection in PET and MRI studies of Alzheimer’s Disease"
Biomarkers of Alzheimer’s disease (AD) such as gray matter volume, white matter hyperintensities, amyloid and Tau are derived from Neuroimaging studies including MRI and PET. There are many challenges in accurately quantifying these biomarkers including technical (i.e., different scanners) as well as clinical manifestation of AD (i.e., atrophy) that require new or improved statistical methods for their quantification. In this work, we present improved statistical methods to address both: technical and clinical challenges. These improvements will be presented on a sample of AD and a sample of control subjects from studies at our institution.
