7T fMRI, AI illustrate how memories help with daily activities
September 21, 2018 -- Could it simply be déjà vu all over again? In a study published online September 19 in Neuron, European researchers used 7-tesla functional MRI (fMRI) scans and artificial intelligence (AI) to determine how the brain connects with a person's memory and past experiences to solve daily problems.  Discuss

High-risk women benefit from twice-yearly breast MRI
September 14, 2018 -- Women at high genetic risk for breast cancer benefit more from twice-yearly dynamic contrast-enhanced breast MRI than from annual mammography, according to research published online August 28 in Clinical Cancer Research.  Discuss
Prostate MRI coverage varies greatly -- with many caveats
September 13, 2018 -- Insurance coverage for prostate MRI scans varies widely among private payors, requires certain conditions for reimbursement of major conditions, and does not reflect current clinical practice. Those harsh conclusions are contained in a new study published online September 11 in the Journal of the American College of Radiology.  Discuss
Research road map drives inquiry into gadolinium's effects
September 12, 2018 -- What's causing gadolinium retention after the use of gadolinium-based contrast agents for MRI scans? Even the most knowledgeable experts don't know for sure, but they hope to clear up some of the confusion with a new research road map unveiled September 11 in a special report published in Radiology.  Discuss
Timing of DWI-MRI predicts breast cancer response
September 11, 2018 -- Diffusion-weighted MR images acquired 12 weeks after the start of neoadjuvant chemotherapy for breast cancer may provide the best indication of how patients will respond to treatment, according to a study published online September 4 in Radiology.  Discuss
AI can distinguish between types of spondylitis on MRI
September 10, 2018 -- An artificial intelligence (AI) algorithm can differentiate between tuberculous spondylitis and pyogenic spondylitis on MRI at a level comparable to that of experienced musculoskeletal radiologists, according to research published online September 3 in Scientific Reports.  Discuss
Is Medicare paying enough for MRI-compatible implants?
September 7, 2018 -- U.S. hospitals could be losing up to $400 million annually on placing MRI-compatible cardiac rhythm management devices in patients due to a discrepancy between what the devices cost and what Medicare is paying for them, according to a new report by group purchasing organization Vizient.  Discuss
MRI shows concussions can loosen brain's myelin
September 6, 2018 -- MR images of hockey players with concussions showed a loosening of protective myelin in the brain two weeks after the injury, even though the skaters felt fine and were declared ready to return to play, according to a study published online August 6 in Frontiers in Neurology.  Discuss
