NEJM: MRI links brain swelling and cerebral malaria deaths
April 17, 2015 -- After three decades of dedication to the care and treatment of children in Malawi who have cerebral malaria, a group of researchers from around the globe for the first time confirmed that brain swelling is the primary reason why some patients die within days from the condition.
Researchers use MRI to watch finger joints crack
April 15, 2015 -- Joint cracking in the fingers appears to be caused by the rapid formation of a gas-filled cavity in the joints' synovial fluid, rather than the collapse of pre-existing bubbles of air as the joints separate, according to a new study in PLOS One that used static and real-time MRI.
Study advises MRI screening for high-risk pancreatic cancer patients
April 8, 2015 -- Swedish researchers believe that MRI could be the best imaging modality to screen people at high risk of pancreatic cancer, according to an April 8 study in JAMA Surgery. In a small study, they showed how using MRI to screen high-risk individuals found pancreatic lesions in 40% of patients.
3T MRI shows how meniscus tears heal, predicts outcomes
April 8, 2015 -- MRI at 3 tesla can help forecast the healing potential of a meniscus tear based, in part, on decreased meniscus extrusion, according to a study presented March 28 at a meeting of the American Orthopaedic Society for Sports Medicine.
Long-term study confirms safety of gadolinium MRI contrast agent
April 1, 2015 -- Amid persistent concerns over the safety of gadolinium MRI contrast agents, a new study published in the April issue of the American Journal of Roentgenology reinforces the "relatively robust safety profile" of at least one MRI agent. Adverse reactions were tracked over nearly eight years and found to be "infinitesimally small."
New MRI technique detects cancer via sugar
March 30, 2015 -- Researchers at Johns Hopkins University have developed an MRI technique that homes in on sugar molecules shed by cancerous cells, potentially offering a new way to differentiate malignant from benign lesions, according to a study published online March 27 in Nature Communications.
Gadolinium persists in brain years after MRI scans
March 27, 2015 -- Researchers from the Mayo Clinic can't quite explain the clinical significance, but the discovery of traces of gadolinium in four areas of the brain several years after administration of MRI contrast is enough evidence to warrant further investigation as to the reasons why.
AGA retreats on workup for pancreatic cysts found on imaging
March 26, 2015 -- The American Gastroenterological Association (AGA) has published new guidelines for managing asymptomatic neoplastic pancreatic cysts detected incidentally during CT or MRI scans. The guidelines retreat from previous advice to follow up these lesions more aggressively, according to an article published in Gastroenterology.
Public reporting does not reduce MRI scans for low back pain
March 26, 2015 -- Healthcare regulators looking to reduce overutilization of medical imaging through public reporting of unnecessary procedures may want to find a bigger stick. An analysis in Texas of public reporting of MRI scans for low back pain -- an often unnecessary procedure -- found the initiative to have little effect on procedure growth.
Brain MRI spots effects of prenatal exposure to air pollutants
March 25, 2015 -- MRI has shown reduced white matter in the brains of children who were exposed to toxic air pollution while in utero. This reduction may have led to behavioral and cognitive problems in the first seven to nine years of their lives, according to an article published online March 25 in JAMA Psychiatry.
