Multiagent imaging of the brain


Positron emission tomography (PET) and single-photon emission computed tomography (SPECT) are in vivo imaging techniques that, using a wide range of tracers, allow the non-invasive tracking of pathophysiological processes in healthy and diseased brain. One of most promising of the various PET and SPECT applications is the investigation of pathophysiological aspects of neurodegenerative disorders. This is an extremely important area of investigation given the aging of the global population and the high prevalence of brain disorders such as Alzheimer’s disease and Parkinson’s disease in elderly persons. Clinical translation of advances in molecular imaging research into clinical practice may, by overcoming the limitations of a diagnostic approach that relies exclusively on clinical judgment and structural imaging, lead to better clinical management of affected patients.
