MRI ties small brain lesions to risk of stroke, death July 7, 2015 -- Asymptomatic patients may have triple the risk of stroke and death if they have brain lesions smaller than 3 mm on 1.5-tesla MRI, a new study concludes. Furthermore, if the patients also have lesions 3 mm or larger, they may face an eightfold increase in stroke risk.
Animal study raises concern over gadolinium contrast agent June 30, 2015 -- A new animal study published online June 22 in Investigative Radiology has linked one class of gadolinium-based contrast agents to increased deposits of the element in the brains of rats, highlighting recent safety concerns about the use of the MRI contrast medium.
DTI-MRI links maternal obesity to newborn brain growth June 26, 2015 -- Infants born to mothers who are obese display altered brain development, according to a new study in which diffusion-tensor MRI (DTI-MRI) showed reduced white-matter integrity in regions of the infants' brains that are associated with cognitive function.
DTI-MRI sheds light on concussion symptoms June 16, 2015 -- Researchers from the University of Pittsburgh Medical Center have uncovered distinct injury patterns in the brain using diffusion-tensor MRI (DTI-MRI) in people with concussion-related depression or anxiety. Results of the new study were published online June 16 in Radiology.
ISMRM 2015: DCE-MRI predicts response to breast chemo June 4, 2015 -- TORONTO - A new method of dynamic contrast-enhanced (DCE) MRI is an "excellent early predictor" of treatment response and a good marker of residual cancer burden during and after neoadjuvant chemotherapy for breast cancer, according to a study at the International Society for Magnetic Resonance in Medicine (ISMRM) meeting.
New high-res 3D MRI map aids surgeons June 4, 2015 -- Researchers at Duke University have created an ultrahigh-resolution 3D MRI map of the human brainstem, intended to help surgeons use deep brain stimulation to treat patients.
ISMRM 2015: MRI detects early signs of cognitive decline June 2, 2015 -- TORONTO - Using an MRI technique known as quantitative susceptibility mapping, Canadian researchers have found evidence of a biomarker that could help differentiate between normal aging and early cognitive decline, according to a study presented on Tuesday at the International Society for Magnetic Resonance in Medicine (ISMRM) annual meeting.
Kids with concussion usually normal on CT, MRI June 2, 2015 -- Most CT and MRI scans performed on children with sports-related concussion are normal, but imaging -- and in particular MRI -- can play a role in determining whether kids are able to return to sporting activities, according to a Canadian study published online June 2 in the Journal of Neurosurgery: Pediatrics.
ISMRM 2015: DTI-MRI may show chemo's side effects in kids June 1, 2015 -- TORONTO - Diffusion-tensor MRI (DTI-MRI) may demonstrate the side effects of chemotherapy in kids treated for a type of glioma by showing lower levels of fractional anisotropy in white matter in the brain, according to a study presented on Monday at the International Society for Magnetic Resonance in Medicine (ISMRM) annual meeting.
VA facility improves patient access to MRI services May 29, 2015 -- By implementing a new appointment and scheduling process and expanding imaging hours, personnel at a U.S. Department of Veterans Affairs (VA) medical center in Virginia have significantly improved patient access to MRI services, according to a study presented at the American College of Radiology's ACR 2015 meeting last week in Washington, DC.
