Vincent Magnotta, a renowned faculty member in the Department of Radiology at the University of Iowa, has successfully obtained funding from the National Institutes of Health to investigate the implications of age-related alterations in brain metabolism, with potential implications for neurodegenerative illnesses such as Alzheimer’s. This research will utilise magnetic resonance spectroscopic imaging (MRSI) technology to further our understanding of the metabolic processes in the brain, particularly in the context of early detection and evaluation of Alzheimer’s and other related dementias.
While conventional magnetic resonance imaging (MRI) has its constraints in capturing images of bodily tissues and organs, MRSI technology offers the potential to reveal metabolic activities within these structures, particularly within the intricate network of the brain. This has considerable promise, as metabolic changes have consistently been associated with Alzheimer’s disease and other cognitive disorders.
However, MRSI technology encounters various technological obstacles, particularly in the form of low image resolution. To address these challenges, Magnotta aims to expand the boundaries of MRSI technology by creating a new framework specifically designed for studying the brain. This will provide healthcare professionals with enhanced capabilities to measure and analyse metabolic changes occurring in the brain.
Due to the strong link between metabolic changes and neurodegenerative disorders, advancements in MRSI technology could revolutionise the screening and early detection of these conditions, perhaps even prior to the emergence of noticeable symptoms. Additionally, researchers may employ this technology as a valuable tool in identifying and assessing treatment targets throughout the brain.
Magnotta is enthusiastic about the potential of the research to facilitate the early identification of Alzheimer’s disease and related dementias. He accentuates the collaborative nature of the research, highlighting the involvement of Mathews Jacob, a faculty member in the Electrical and Computer Engineering department at the College of Engineering, and Yan Li from the University of California-San Francisco, all of whom are recognised as co-principal investigators on the grant.
This substantial five-year grant, amounting to $3.9 million, was awarded by the National Institute on Aging.
In summary, this notable funding will advance the capabilities of MRSI technology, offering an innovative opportunity to investigate age-related alterations in brain metabolism and contribute to the early identification and potential interventions for Alzheimer’s disease and related dementias.
