fMRI finds where God might dwell in the brain
November 29, 2016 -- When people have a religious and spiritual experience, reward-related regions of the brain become illuminated on functional MRI (fMRI) scans, much the same way these areas react to love, sex, gambling, drugs, and music, according to a study published November 29 in Social Neuroscience.
DTI shows how music could help kids with autism, ADHD
November 23, 2016 -- Diffusion-tensor MR images (DTI-MRI) of the brain have revealed that taking music lessons increases brain fiber connections in children and may help those with autism and attention deficit hyperactivity disorder (ADHD). The findings are scheduled for presentation on November 30 at RSNA 2016.
Switch to macrocyclic GBCAs reduces brain signals
November 21, 2016 -- As more studies weigh the risks and benefits of gadolinium-based contrast agents (GBCAs), German researchers have discovered that switching from a linear GBCA to a macrocyclic GBCA reduced the level of residual signal intensity in the brains of patients who underwent multiple enhanced MRI scans with both types of agents.
MRI signals may show residual GBCA effects in the brain
November 11, 2016 -- As researchers explore the potential long-term effects of gadolinium-based contrast agents (GBCAs), the direct measurement on MRI scans of T1 and T2 signal intensities in the brain may become a reliable method, according to a study published online October 31 in Radiology.
Gadobutrol causes 'very low' number of allergic-like reactions
November 9, 2016 -- As radiologists and clinicians maintain their vigilance over the judicious use of gadolinium-based contrast agents for MRI scans, a new prospective study in Radiology has found that one agent, gadobutrol, resulted in a very low number of allergic-like reactions.
fMRI beats polygraph test in detecting lies
November 7, 2016 -- The next time you think someone is telling a lie, give them a functional MRI (fMRI) scan instead of a polygraph test. Researchers found that fMRI experts were 24% more likely to detect a deception on fMRI than polygraph examiners were using polygraphy.
DTI-MRI charts brain changes in young football players
October 24, 2016 -- Diffusion-tensor MRI (DTI-MRI) scans have shown significant brain changes in young football players after just one season of games and practice, even when they appear concussion-free, according to a new study published online October 24 in Radiology.
Abstinence before prostate MRI offers benefits in over 60s
October 5, 2016 -- Abstinence from ejaculation prior to a prostate MR examination significantly increases the volume of seminal vesicles (SVs), and thereby may well improve evaluation of SV invasion on multiparametric MRI, especially in older men, according to new research from Turkey and the U.S.
Rat study finds no brain abnormalities from GBCAs
October 4, 2016 -- An evaluation of two linear gadolinium-based contrast agents (GBCAs) showed no signs of abnormalities in the brains of rats despite the presence of gadolinium. What's more, researchers found that gadolinium levels had decreased markedly 20 weeks after GBCA injection, according to results published online September 27 in Radiology.
MRI initiative will chart brain development in children
September 22, 2016 -- Researchers at the University of North Carolina at Chapel Hill and the University of Minnesota are about to embark on a groundbreaking four-year journey to track and analyze the highly dynamic evolution of a child's brain between birth and age 5 through regularly scheduled MRI scans.
