FDA readies new safety probe into gadolinium contrast
August 25, 2015 -- Once again, the U.S. Food and Drug Administration (FDA) is set to embark on an investigation into the safety of gadolinium-based contrast agents, after several recent studies found gadolinium deposits in the brains of some patients years after they had received contrast-enhanced MRI scans.
MRI finds brain changes in boys who faced adversity
August 19, 2015 -- MRI scans have found that boys who faced challenges during the first six years of their lives had less cortical gray brain matter and altered brain structure by the time they reached their late teens or early 20s, according to a study published online August 17 in JAMA Pediatrics.

fMRI goes to the dogs in new study of canine brains
August 5, 2015 -- Have you ever wondered what your Fido is thinking when he sees another dog? Researchers from Emory University wanted to answer that question, so they used functional MRI (fMRI) to scan the brains of dogs while the animals looked at pictures of other canines as well as humans.
MRI links cardiac risk factors to cognition problems
July 28, 2015 -- MRI scans have demonstrated smaller regional brain volumes in people with certain cardiovascular risk factors, which could put them at risk for developing adverse cognitive issues, according to a study published online July 28 in Radiology.
