MRI could be 'game changer' for cardiac arrest survivors
October 19, 2017 -- By taking MRI measurements of the brain's functional network connectivity within two weeks after a patient experiences cardiac arrest, clinicians may be better able to predict their clinical outcomes, according to a study published online October 18 in Radiology.  Discuss
DTI-MRI poses new cause for schizophrenia
October 19, 2017 -- Disruptions in the connectivity of the brain's white matter, as seen on diffusion-tensor MR images (DTI-MRI), could play a larger role in schizophrenia than previously thought, according to a study published online October 17 in Molecular Psychiatry.  Discuss
Deep learning can enable quantitative MRI for arthritis
October 16, 2017 -- A deep-learning algorithm can accurately segment knee MRI scans and extract quantitative data in seconds, potentially helping radiologists to easily provide clinicians with valuable data for diagnosing, assessing, and treating osteoarthritis, according to a team from the University of California, San Francisco.  Discuss
fMRI reveals that 'magic mushrooms' reduce depression
October 13, 2017 -- U.K. researchers used functional MRI (fMRI) to determine that the psychoactive ingredient in "magic mushrooms" -- psilocybin -- decreases symptoms of depression, according to a study published online October 13 in Scientific Reports.  Discuss
Biomarker test could direct MRI use for prostate cancer
October 13, 2017 -- Dutch researchers are reporting promising results using a new urinary biomarker risk-scoring system to test for the possibility of prostate cancer. The test could be used to select which patients should be sent on for additional MRI scans or biopsy, according to a study published in the October issue of The Prostate.  Discuss
FDA clears 7-tesla MRI scanner from Siemens
October 12, 2017 -- The U.S. Food and Drug Administration (FDA) has cleared Magnetom Terra from Siemens Healthineers, the first 7-tesla MRI scanner cleared for clinical use in the U.S.  Discuss
One-third of MRI exam time is wasted
October 11, 2017 -- Wasted time represents a third of the total MRI exam process cycle -- and it can also extend a patient's length of stay in the hospital, according to research published in the October issue of the American Journal of Roentgenology.  Discuss
Evidence mounts: Use macrocyclic GBCAs in pediatric MRI
October 6, 2017 -- Could macrocyclic gadolinium-based contrast agents (GBCAs) become the standard MRI protocol for pediatric patients? German researchers think so, after finding no measurable increase in signal intensity in key brain regions after multiple administrations in a study published in the October issue of Radiology.  Discuss
MRI advances detection of Zika-related brain abnormalities
October 4, 2017 -- MRI should be combined with ultrasound to provide additional information to assess fetal brain development in pregnant women who have been exposed to or infected by the Zika virus, according to new research presented this week at the IDWeek 2017 conference in San Diego.  Discuss
IBM's Watson assigns patients to MRI contrast
October 3, 2017 -- Determining which patients need contrast for musculoskeletal MRI scans can soak up a lot of time and resources. What if you could use artificial intelligence instead? Researchers found that IBM Watson could help optimize the process, according to a September 18 paper in the Journal of Digital Imaging.  Discuss
