New protocol enables faster, cheaper cardiac MRI scans
August 30, 2018 -- Researchers have developed a rapid contrast-enhanced cardiac MRI protocol that can measure structure, function, and scarring in the heart in less than 20 minutes and at considerably lower cost than standard MRI protocols, according to results published on August 29 in the Journal of the American Heart Association.  Discuss
MRI shows drug slows brain atrophy in MS patients
August 29, 2018 -- MR images from more than 200 patients with progressive multiple sclerosis (MS) show that a promising anti-inflammatory drug can decrease the progression of brain atrophy by 48% compared with a placebo, according to a study in the August 30 issue of the New England Journal of Medicine.  Discuss
Facebook, NYU feel need for MRI speed with AI
August 24, 2018 -- Can less really be more in MRI? Facebook and New York University (NYU) intend to find out with the launch of fastMRI, a collaborative project that aims -- with the help of artificial intelligence (AI) -- to make MRI scans up to 10 times faster by reconstructing diagnostic-quality images using much less raw data.  Discuss
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
