Studies question link between contact sports and CTE
August 10, 2018 -- Are concerns about the brain health of professional athletes who played contact sports overblown? That's the implication of a new study that found no signs of brain abnormalities on MRI scans of former hockey and football players that would suggest the presence of chronic traumatic encephalopathy (CTE).  Discuss
AI characterizes complex mood disorders from fMRI
August 9, 2018 -- An artificial intelligence (AI) algorithm can distinguish patients with major depressive disorder from those who have bipolar disorder based on an analysis of functional MRI (fMRI) studies, according to research published online August 6 in Acta Psychiatrica Scandinavica.  Discuss
Variation in CT, MRI protocols can be reduced
August 8, 2018 -- Researchers from Boston successfully cut by almost one-third the number of CT and MRI protocols being used in their health network. They believe the streamlining will lead to more consistent patient care with less waste, according to an article published online August 3 in the Journal of the American College of Radiology.  Discuss
Bearded men pose greater hygiene risk than dogs in MRI
August 3, 2018 -- Patients should not feel unduly concerned if a dog was the previous visitor to the MRI unit, but they should worry if a bearded man has just been scanned. That's the key finding of a novel Swiss-led infection study published online by European Radiology on July 30.  Discuss
Who reads lower-extremity MRI exams and why?
August 3, 2018 -- Most lower-extremity MRI exams are still interpreted by radiologists, but those that are read by nonradiologists are more likely to have been performed during the week and to be less complex cases, according to a study published online July 31 in the American Journal of Roentgenology.  Discuss
MRI quality training comes up short
August 3, 2018 -- A study conducted by Irish and Saudi researchers into opinions and attitudes among MRI professionals has revealed that radiographers have a low participation rate in quality assurance testing and may rely too heavily on equipment vendors for ongoing scanner performance.  Discuss
Soccer ball heading more risky for women than men
July 31, 2018 -- Heading a soccer ball may not always be the safest play on the pitch. Diffusion-tensor MRI has revealed that female soccer players have more microstructural white-matter changes in brain tissue than their male counterparts, according to a study published online July 31 in Radiology.  Discuss
Language issues don't greatly delay MRI scans
July 31, 2018 -- At least one radiology department is not letting language barriers get in the way of timely MRI scans. Researchers in Michigan found no significant difference in wait times between patients who spoke English and those who didn't, according to a study published online July 26 in the Journal of the American College of Radiology.  Discuss
MRI finds key indicators of rectal cancer prognosis
July 31, 2018 -- Two key characteristics on MRI scans of rectal cancer patients can help predict long-term survival and local recurrence of the disease, according to a study by researchers from China and published in the August issue of the American Journal of Roentgenology.  Discuss
VR software may increase MRI segmentation efficiency
July 26, 2018 -- Using new virtual reality (VR) software to correct segmentation errors on MRI scans allowed users to complete the task more quickly and accurately compared with using a conventional 2D interface in a new study, published online July 20 in the Journal of Digital Imaging.  Discuss
