Gadolinium may enter brain via CSF in humans
August 24, 2018 -- Swiss researchers have confirmed the presence of gadolinium in cerebrospinal fluid (CSF) within a few hours of an MRI scan with a macrocyclic gadolinium-based contrast agent. The findings indicate that CSF could be the pathway through which gadolinium enters the brain, they concluded in the September issue of Radiology.  Discuss
fMRI shows dehydration's effect on the brain
August 23, 2018 -- Functional MR images (fMRI) have revealed changes in the brain's ventricles and thalamus based on water intake in people who exercise under strenuous conditions, according to a study published online August 22 in Physiological Reports.  Discuss
MRI links lifestyle factors to stroke, dementia risk
August 21, 2018 -- Using MRI, researchers found that lifestyle factors can increase the risk of stroke and dementia later in life among young adults with no clinical evidence of cerebrovascular disease and a seemingly healthy cardiovascular risk profile. The study was published in the August 21 issue of the Journal of the American Medical Association.  Discuss
MRI helps find contact lens embedded in eye for 28 years
August 17, 2018 -- With the help of MRI, ophthalmologists in the U.K. were able to discover what was causing eyelid swelling in a 42-year-old woman: a hard contact lens that had been embedded in her eye for 28 years. The bizarre case was published on August 10 in BMJ Case Reports.  Discuss
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
