Abstract: With Alzheimer’s disease (AD) quickly becoming the most costly disease to society, and with no disease-modifying 
treatment currently, prevention and early detection have become key points in AD research.  Important features within this research 
focus on understanding disease pathology, as well as finding biomarkers that can act as early indicators and trackers of disease 
progression or potential treatment.  With the advances in neuroimaging technology and the development of new imaging techniques, 
the search for cheap, noninvasive, sensitive biomarkers becomes more accessible.  Modern neuroimaging techniques are able to 
cover most aspects of disease pathology, including visualization of senile plaques and neurofibrillary tangles, cortical atrophy, 
neuronal loss, vascular damage, and changes in brain biochemistry.  These methods can provide complementary information, 
resulting in an overall picture of AD.  Additionally, applying neuroimaging to animal models of AD could bring about greater 
understanding in disease etiology and experimental treatments whilst remaining in vivo.  In this review, we present the current 
neuroimaging techniques used in AD research in both their human and animal applications, and discuss how this fits in to the 
overall goal of understanding AD. (ajnmmi1206001).
