Abstract

The development of a noninvasive method to detect early, subtle changes in the brains of patients with Alzheimer's disease (AD) would have considerable clinical value as therapy. This therapy is most likely to be successful if intervention could occur before neurons were irreversibly damaged or lost. An ideal biological neuroimaging marker would be an early, sensitive, and valid indicator of brain changes, capable of discriminating the effects of normal aging. The introduction of high field-strength clinical magnetic resonance imaging (MRI) systems now offer a powerful new noninvasive tool that may be capable of detecting brain pathology resulting from AD. Here we present results from high field-strength MRI in transgenic mice along with a new MRI technique for imaging brain iron. The successful translation of this research to the clinic could prove important to both the early diagnosis and monitoring of the efficacy of potential therapies in humans.
