A retrospective, five-year study of 1,314 patients with multiple sclerosis (MS) has found that atrophied brain lesion volume is the only marker from MRI scans that can accurately predict which patients will progress to the most severe form of the disease. Secondary progressive MS, known as SPMS, typically appears 10 to 20 years after the initial onset and causes patients […]

Calcium is a critical signaling molecule for most cells, and it is especially important in neurons. Imaging calcium in brain cells can reveal how neurons communicate with each other; however, current imaging techniques can only penetrate a few millimeters into the brain. MIT researchers have now devised a new way to image calcium activity that is based on magnetic resonance […]

An MRI scan often generates an ocean of data, most of which is never used. When overlooked data is analyzed using a new technique developed at Washington University School of Medicine in St. Louis, they surprisingly reveal how many and which brain cells are present – and show where cells have been lost through injury or disease. The findings, published […]

Getting magnetic resonance imaging (MRI) scans twice a year instead of one annual mammogram is far more effective at detecting early breast cancers in young women with a high-risk genetic profile than mammograms alone, according to a research team based at the University of Chicago Medicine and the University of Washington, Seattle. The results, first presented Dec. 8, 2017 at […]

Ever wonder why some people seem to feel less pain than others? A study conducted at Wake Forest School of Medicine may have found one of the answers—mindfulness. “Mindfulness is related to being aware of the present moment without too much emotional reaction or judgment,” said the study’s lead author, Fadel Zeidan, Ph.D., assistant professor of neurobiology and anatomy at […]

Neuroscience researchers have long used Magnetic Resonance Imaging to study the basic structure of the brain in health and disease, but MRI scanners can’t typically provide insights at the cellular level. In an MRI image, each voxel—the 3-D equivalent of a pixel—represents tens of thousands of brain cells. A breakthrough study led by the Mark and Mary Stevens Neuroimaging and […]
