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
MRI protocol syncs brain motion with cardiac rhythm
May 30, 2018 -- Researchers from the U.S. and Australia may be on the verge of capturing one of radiology's holy grails: an MRI technique that visualizes the real-time motion of blood and spinal fluid in the brain with every heartbeat. Their progress was published online May 29 in Magnetic Resonance in Medicine.  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
Quantitative MRI could advance prostate cancer detection
May 24, 2018 -- Researchers are reporting early success with a novel quantitative MRI technique designed to calculate changes in tissue volume within the prostate to improve the diagnosis of cancer and better evaluate its aggressiveness, according to a study published in the June issue of Radiology.  Discuss
Novel MRI scanner fits extremity imaging like a glove
May 22, 2018 -- Extremity imaging may never be the same if researchers from NYU Langone Health have their way. They are developing an MRI device that fits over a patient's hand like a glove to image moving joints, as detailed in a study published May 8 in Nature Biomedical Engineering.  Discuss
FDA adds 8 gadolinium MRI agents to medication guide
May 18, 2018 -- The U.S. Food and Drug Administration (FDA) is continuing to update its information for patients, clinicians, and other healthcare practitioners regarding gadolinium-based contrast agents (GBCAs) by adding eight GBCA products to its medication guide.  Discuss
MRA tops CTA for pulmonary embolism evaluation
May 16, 2018 -- MR angiography (MRA) may have an edge over CT angiography (CTA) for diagnosing pulmonary embolism due to its reduced risk of radiation and adverse events, according to a pair of articles by Wisconsin researchers published online in Emergency Radiology and the Journal of the American College of Radiology.  Discuss
