MRI shows concussion effects last longer than thought
October 17, 2019 -- MR images have revealed lingering abnormalities in the brains of concussed athletes more than a year after they were cleared to return to competition, which could mean the injuries have not yet completely healed, according to a study published online on October 16 in Neurology.  Discuss
fMRI maps show dementia spreading through brain networks
October 16, 2019 -- Brain maps based on functional MRI (fMRI) scans are proving useful in predicting the spread of brain atrophy that leads to progressive dementia, according to a study published October 14 in Neuron.  Discuss
Do steroid injections into joints do more harm than good?
October 15, 2019 -- X-ray imaging shows that corticosteroid injections for osteoarthritis pain in the hip and knee may actually damage the joints, leading to more rapid progression of the disease and eventually joint collapse, according to a study published online October 15 in Radiology.  Discuss
MRI links head trauma microbleeds to clinical outcome
October 15, 2019 -- MRI scans of patients with traumatic head injuries have revealed microbleeds that appear as dark lesions and are often too small for detection on CT, according to a study published on October 14 in Brain.
fMRI links mood disorders to greater suicide risk
October 14, 2019 -- The ability of resting-state functional MRI (fMRI) to pinpoint reduced brain connectivity in individuals with mood disorders could help clinicians detect people who might become suicidal, according to a study published October 10 in Psychological Medicine.  Discuss
