| pubmed-article:16932505 | pubmed:abstractText | Alois Alzheimer first imaged amyloid plaques in 1906 by examining dead tissue under the microscope, but their clinical significance has remained undetermined. Now, nearly a century later, investigators are beginning to image amyloid plaques in living brains using both positron emission tomography and MRI. In this article, we review the studies that report on these recent technical advances, and discuss their potential importance in clarifying the diagnostic and pathogenic relevance of amyloid plaques to Alzheimer's disease. | lld:pubmed |
