Cardiac PET/MRI protocol reduces radiation dose
April 21, 2016 -- Researchers have developed a new cardiac PET/MRI protocol with sodium fluoride that significantly reduces radiation dose and artifacts, enhancing the view of disease activity in coronary arteries.
ARRS: Metal fragments in veterans can make MRI dicey
April 20, 2016 -- LOS ANGELES - Can MR be used safely in patients like combat veterans, who often have retained metal fragments in their bodies? Yes, but proceed with caution, according to research presented at the American Roentgen Ray Society (ARRS) meeting.
Imaging holds key in war on drug mules

MRI shows brain injury in nearly half of ex-NFL players
April 11, 2016 -- Researchers have found signs of traumatic brain injury on diffusion-tensor MR images in nearly half of a small group of retired NFL players, according to a study scheduled for presentation next week at the American Academy of Neurology annual meeting in Vancouver, British Columbia, Canada.
Researchers: Gadolinium removal drug is needed
April 7, 2016 -- A new review of the literature on gadolinium-based contrast agents for MRI scans has found a "significant gap in knowledge" on the health effects of gadolinium accumulation in tissue. Researchers are calling for new clinical studies, as well as the development of a drug that would remove retained gadolinium from the body.
DTI-MRI unlocks mysteries of insomnia

fMRI shows how mindfulness training can help veterans
April 4, 2016 -- Functional MRI (fMRI) showed changes in two areas of the brain in military veterans with post-traumatic stress disorder (PTSD) who improved their ability to manage thoughts through mindfulness training, according to a study in the April issue of Depression and Anxiety.
MRI offers insight into brain changes from concussion
March 31, 2016 -- With the help of MRI, Canadian researchers have created for the first time in vivo images of myelin damage in the human brain after a sports-related mild traumatic brain injury -- in this case in Canadian hockey players.
Breast MR: Is it accessible to women who need it?
March 30, 2016 -- MR is an effective breast cancer screening tool for women with a higher lifetime risk of the disease. But its availability can be limited, and sociodemographic factors may play more of a role in access than women's breast cancer risk factors, according to a new study published in the Journal of the American College of Radiology.
DTI helps predict mild TBI outcomes in veterans
March 29, 2016 -- Diffusion-tensor MRI (DTI-MRI) could play a key role in predicting military veterans' functional postdeployment outcomes -- such as how soon they return to work -- following a mild traumatic brain injury (TBI) during combat, according to a new study published online March 29 in Radiology.
