3DHeals conference explores 3D printing and more
March 22, 2017 -- 3D printing is revolutionizing medicine -- and radiology with it. But what's the best way to learn about this emerging discipline? The 3DHeals International Conference, being held in San Francisco on April 20, will explore 3D printing in healthcare with an eye on virtual reality, augmented reality, and artificial intelligence.
Can cloud-based archiving cure your security headaches?
March 22, 2017 -- Longstanding U.S. healthcare regulations have enforced the security of data from reasonably anticipated threats, and new -- even stricter -- guidelines related to data access and backup aim to create additional layers of security and integrity. However, the majority of departmental PACS archiving or disaster recovery systems fail to fully support these initiatives, according to Ed Marshall from Ambra Health.
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.
Medicare imaging use varies widely at county level
March 20, 2017 -- In the Medicare population, imaging use and costs vary far more at the county level than at the state level, according to a new study published online March 10 in the Journal of the American College of Radiology.
ACC: CT detects blood clots that reduce valve motion
March 20, 2017 -- CT detects small clots surrounding valve leaflets after transcatheter aortic valve replacement that are missed on echocardiography studies, concludes new research presented at the just-concluded American College of Cardiology (ACC) meeting in Washington, DC. Reduced valve motion after the procedure may be a sign of the condition, the researchers said.
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.
Adding DBT to breast screening helps BI-RADS accuracy
March 17, 2017 -- More and more clinical evidence indicates that using digital breast tomosynthesis (DBT) for breast cancer screening reduces recall rates and increases the detection of invasive cancers. Now another benefit of the technology is coming to the fore: Adding DBT to digital mammography helps breast imagers categorize lesions more accurately, according to research presented at ECR 2017.
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.
