Image: The study by Kep Kee Loh and Dr. Ryota Kanai found that gray-matter density in the highlighted region of the brain (anterior cingulate cortex) in MR images was negatively associated with the amount of media multitasking activity (Photo courtesy of the University of Sussex).

fMRI Neuro Scans Reveal Gray Matter Disparities in Media Devices Multitaskers

By simultaneously using laptops, cell phones, and other media devices, people could be changing their brain structure. A study reveals that individuals who frequently use several media devices used concurrently have lower gray-matter density in one specific region of the brain compared to those who use just one device occasionally.  More...

MRI Technology Enables Noninvasive Monitoring of Emergent Cell Therapies

Cellular therapeutics, the application of using intact cells to treat and cure disease, is an important potential new therapeutic application, but it is hampered by the inability of clinicians and scientists to effectively monitor the destination, movements, and perseverance of these cells in patients without having to use invasive procedures, such as tissue sampling.   More...

Image: Simplified illustration shows disease simulation model. Patients start in the 70%– 89% luminal narrowing state and progress or regress to other narrowing states, experience a stroke, undergo revascularization (revasc), or die of stroke-related or nonstroke-related causes (Photo courtesy of the Radiological Society of North America).

fMRI Identifies Asymptomatic Individuals at Risk for Stroke

Imaging can be a cost-effective way to identify people at risk for stroke who might benefit from aggressive intervention, according to a new modeling study.  More...
