Pediatric radiology abandons linear gadolinium contrast
March 21, 2017 -- Concerns over possible gadolinium retention in the brain have prompted more than half of surveyed pediatric radiology departments in the U.S. to switch from a linear gadolinium-based contrast agent (GBCA) to a macrocyclic GBCA within the past year, according to a study published online March 10 in Pediatric Radiology.
Mobile App Spotlight: A k-Space Odyssey
March 21, 2017 -- presents the next article in an ongoing series highlighting notable mobile apps in radiology. In this installment, we take a look at A k-Space Odyssey, an iOS app designed to facilitate understanding of k-space, the mathematical abstraction that connects MRI scan parameters with the clinical image.
MRI shows less gray matter in kids with sleep apnea
March 20, 2017 -- MRI scans have revealed significant reductions of gray matter in several brain regions of children with moderate or severe obstructive sleep apnea, compared with children who sleep normally, according to a paper published online March 17 in Scientific Reports, one of the Nature journals.
MRI can replace biopsy for prostate cancer surveillance
March 17, 2017 -- MRI can be used in place of serial biopsy as part of an active surveillance program for prostate cancer, complementing prostate-specific antigen levels and digital rectal exams in early-stage patients. The combination could help guide who needs treatment without the need for biopsy, according to a study in the March issue of the American Journal of Roentgenology.
Patient group campaigns for gadolinium research, answers
March 16, 2017 -- With all the scientific debate in recent years over the long-term effects of gadolinium retention after contrast-enhanced MRI scans, two patients are leading a campaign to advance research on the topic and, most importantly, ensure that those adversely affected by gadolinium are heard and not forgotten.
No signal intensity for pediatric patients with macrocyclic GBCA
March 15, 2017 -- German researchers have found additional evidence that the use of a macrocyclic gadolinium-based contrast agent (GBCA) for MRI scans does not increase signal intensity in the dentate nucleus. The new findings come from a study of pediatric patients published online in Radiology.
Pull linear MRI contrast from market, European group says
March 10, 2017 -- In a stunning development, a European Union regulatory body on Friday recommended that four gadolinium-based contrast agents for MRI scans be pulled off the market due to concerns about gadolinium remaining in the body years after scans occur. The agents affected include some of the most widely used contrast products in medical imaging.
SIR: MRI debunks venoplasty for treating MS
March 9, 2017 -- Opening up narrowed veins from the brain and spinal cord -- a procedure called venoplasty -- is not effective for treating multiple sclerosis (MS), according to a study presented on March 8 at the Society of Interventional Radiology (SIR) meeting in Washington, DC, by researchers from the University of British Columbia.
Direct invitations boost breast MRI screening rates
March 9, 2017 -- Women at high risk of breast cancer who receive letters that outline their options for additional imaging with contrast-enhanced MRI are more likely to follow through on this additional imaging, according to a study published online February 3 in Health Communication.
MRI links early brain abnormality in infants to autism
March 8, 2017 -- Using MR imaging, researchers have found that children diagnosed with autism at 2 years of age had a substantially greater amount of extra-axial cerebrospinal fluid when they were 6 and 12 months old, according to a study published online March 6 in Biological Psychiatry.
