MRI scans show neckties cut blood flow to brain
July 5, 2018 -- You now have another reason to hate neckties. German researchers using MRI discovered that neckties can constrict blood flow to the brain, according to a study published online June 30 in Neuroradiology.  Discuss
MRI links inflammation to cognitive decline
July 3, 2018 -- Using MRI, researchers have found that chronic inflammation measured by a biomarker in the blood of middle- to late-age adults could be linked to visible white-matter damage in the brain and related poor cognition and dementia, according to a study in the August issue of Neurobiology of Aging.  Discuss
MRI brain scans show benefits of prenatal folic acid
July 3, 2018 -- MRI scans show that adolescents whose mothers received food enriched with folic acid while they were pregnant have enhanced brain development and a reduced risk of psychosis and other mental illnesses as they progress toward adulthood, according to a study published online July 3 in JAMA Psychiatry.  Discuss
Are patients with cardiac devices missing out on MRI?
July 2, 2018 -- Many patients who have older implanted cardiac devices are not getting brain and spine MRI scans, even though recent studies have shown that MRI can be safely performed on people with these legacy devices. That's according to a new article published July 2 in JAMA Neurology.  Discuss
Macrocyclic GBCA shows no signal increase in kids
June 29, 2018 -- Five or more doses of the macrocyclic gadolinium-based contrast agent (GBCA) gadobutrol resulted in no increase in T1-weighted signal-intensity ratios in the globus pallidus or dentate nucleus of pediatric patients, a sign of no gadolinium deposition in these patients, according to a June 26 paper in Radiology.  Discuss
7T MRI may release mercury from amalgam dental fillings
June 26, 2018 -- MR imaging at 7-tesla magnet strength may release toxic mercury from amalgam dental fillings, according to a new study published online June 26 in the journal Radiology. However, the effect was not found with the lower-strength 1.5-tesla magnets that are more commonly used in the clinical setting, the researchers noted.  Discuss
Fetal MRI scans might foretell effects of severe anemia
June 22, 2018 -- Fetal MRI brain scans can advance the detection of abnormalities due to severe fetal anemia and correlate subsequent deficiencies with poor neurological development, according to a French study published online June 6 in the European Journal of Obstetrics and Gynecology and Reproductive Biology.
AI algorithm registers MRI scans in under 1 second
June 20, 2018 -- Researchers have developed an artificial intelligence (AI) algorithm capable of registering MRI scans roughly 1,000 times faster than standard methods can, according to a poster presentation at the Computer Vision and Pattern Recognition event this week in Salt Lake City.  Discuss

Sodickson: ISMRM can play sheriff in AI's Wild West
June 19, 2018 -- The imaging artificial intelligence (AI) landscape is like the Wild West right now, but the International Society for Magnetic Resonance in Medicine (ISMRM) can act as the sheriff, according to Dr. Daniel Sodickson, PhD, the society's president.  Discuss
