fMRI scans may help choose depression treatment strategy March 27, 2017 -- Researchers using functional MRI (fMRI) have found specific patterns of brain activity that may help determine whether behavioral therapy or antidepressant medication is better for patients with depression, according to research published online March 24 in the American Journal of Psychiatry.
ACA repeal effort falls short as GOP can't muster votes March 24, 2017 -- Republicans have shelved legislation that would have repealed the Affordable Care Act (ACA) -- known colloquially as Obamacare. In a March 24 press conference, President Donald Trump acknowledged the failure of the repeal effort and said his administration will now move on to other priorities, such as tax reform.
3D printers help build a better cranial nerve March 24, 2017 -- Researchers have created a high-resolution model of a 3D-printed brain and skull base from CT and MR images that details the cranial nerves in ways that outperform standard diagnostic images. The complex neuroanatomy of the nerves can be better understood and depicted by the use of highly customizable 3D-printed models, according to a report in the Journal of Digital Imaging.
Can deep-learning CAD outperform mammographers? March 23, 2017 -- Can computer-aided detection (CAD) software developed with deep-learning technology perform better than mammographers? Yes it can, at least for the task of differentiating between benign and malignant calcifications, according to a team of researchers from California.
How useful are second opinion breast imaging reads? March 23, 2017 -- A second opinion review of breast images from other institutions leads to a change in interpretation -- and potentially disease management decisions -- in almost 30% of patients, according to a study published online March 16 in the American Journal of Roentgenology.
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 -- AuntMinnie.com 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.
