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
Breast MRI underutilized in high-risk women
June 20, 2018 -- Supplemental screening breast MRI is underused by women at higher risk of breast cancer, according to a study published in the June issue of the Journal of Women's Health.  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
ASL-MRI connects kidney and cognitive dysfunction
June 12, 2018 -- Using arterial spin labeling (ASL) MRI, researchers have found that increased cerebral blood flow in children and young adults with chronic kidney disease correlates with subsequent decreased cognitive function, according to a study published online June 12 in Radiology.  Discuss
Faster MRI protocol avoids unneeded prostate biopsies
June 8, 2018 -- The use of a streamlined MRI protocol could help reduce unnecessary biopsies by as much as 30% in men suspected of having prostate cancer, according to a study published online June 8 in JAMA Network Open.  Discuss
MRI shows potentially better indicator for MS progression
June 6, 2018 -- Using MRI scans to view brain lesions in patients with multiple sclerosis, researchers at the University at Buffalo are contradicting a decades-long belief on how to determine whether the condition will progress. Their results were published online June 1 in the Journal of Neuroimaging.  Discuss
SIIM: AI can accurately detect cerebral microbleeds
June 4, 2018 -- An artificial intelligence (AI) algorithm can automatically identify radiation-induced cerebral microbleeds on brain MRI scans with a high degree of sensitivity, according to research presented on Saturday at the Society for Imaging Informatics in Medicine (SIIM) annual meeting in National Harbor, MD.  Discuss
Animal study finds gadolinium retention tied to GBCA type
May 29, 2018 -- A study performed in mice has found that the amount of gadolinium retained in the brain after the administration of a gadolinium-based contrast agent (GBCA) depends heavily on whether the agent was linear or macrocyclic. The results were published May 22 in Radiology.  Discuss
