Artificial Intelligence Accelerates MRI Parameter Mapping

In Magnetic Resonance Imaging, Georges El Fakhri, PhD, director of the Gordon Center for Medical Imaging in the Department of Radiology at Massachusetts General Hospital, and Fang Liu, PhD, a researcher in the center, and colleagues describe their newest effort, a method that rapidly creates realistic MRI parameter maps by incorporating adversarial training into a previously created deep learning framework.

Sepulcre article in Nature Medicine

Dr. Jorge Sepulcre, an Assistant Professor of Radiology at HMS and Assistant in Neuroscience at the MGH Gordon Center, leads a lab that focuses on brain imaging studies aimed at the understanding of large-scale brain networks implicated in human cognition and neurodegenerative disorders. His article titled “Neurogenetic contributions to amyloid beta and tau spreading in the human […]

Refining Models of Amyloid Accumulation in Alzheimer’s Disease

“PET staging of amyloidosis using striatum”: A new study published in Alzheimer’s and Dementia, the Journal of the Alzheimer’s Association, proposes to stage amyloid PET images using regional information. The research was conducted by Dr. Bernard Hanseeuw, instructor at MGH Gordon Center, and Dr. Keith Johnson, leader of the Aging NeuroImaging Program at the MGH Gordon Center, and the Harvard Aging Brain Study.

Novel PET Imaging Tracer May Improve Monitoring of Multiple Sclerosis

In a recent paper published by the journal Scientific Reports, Dr. Pedro Brugarolas and his colleagues describe the development and testing in animal models of a new PET tracer for demyelination. Their new tracer is based on the MS drug 4-aminopyridine (4AP, dalfampridine) which binds to potassium channels in demyelinated axons allowing the visualization of demyelinated lesions in animal models of MS noninvasively.
