MRI for all: Cheap portable scanners aim to revolutionize medical imaging
.news-article__hero--featured .parallax__element{ object-position: 47% 50%; -o-object-position: 47% 50%; } The patient, a man in his 70s with a shock of silver hair, lies in the neuro intensive care unit (neuro ICU) at Yale New Haven Hospital. Looking at him, you’d never know that a few days earlier a tumor was removed from his pituitary gland. The operation didn’t leave a mark because, as is standard, surgeons reached the tumor through his nose. He chats cheerfully with a pair of research associates who have come to check his progress with a new and potentially revolutionary device they are testing. The cylind...

Cardiac imaging dev VerAvanti raises $5m
Previously-stealthy cardiac imaging developer VerAvanti said today it raised $5 million in a recent round of financing to support its Scanning Fiber Endoscope device development. The Redmond, Wash.-based company’s SFE device uses technology licensed from the University of Washington and consists of an imaging station and micro-sized catheter which can take high-quality images inside of vessels to improve the diagnosis and treatment of stroke and other heart conditions. VerAvanti said that it has received 2 NIH research Phase 1 grants totaling $586,000 in May and June, alongside support from the company’s founder Ge...

More Research Is Needed on Lifestyle Behaviors That Influence Progression of Parkinson's Disease
This article highlights some of these challenges in the design of lifestyle studies in PD, and suggests a more coordinated international effort is required, including ongoing longitudinal observational studies. In combination with pharmaceutical treatments, healthy lifestyle behaviors may slow the progression of PD, empower patients, and reduce disease burden. For optimal care of people with PD, it is important to close this gap in current knowledge and discover whether such associations exist. Introduction Parkinson's disease (PD) is an age-related complex progressive neurodegenerative disorder, with key p...

How AI Is Changing Medical Imaging to Improve Patient Care
That doctors can peer into the human body without making a single incision once seemed like a miraculous concept. But medical imaging in radiology has come a long way, and the latest artificial intelligence (AI)-driven techniques are going much further: exploiting the massive computing abilities of AI and machine learning to mine body scans for differences that even the human eye can miss. Imaging in medicine now involves sophisticated ways of analyzing every data point to distinguish disease from health and signal from noise. If the first few decades of radiology were about refining the resolution of the pictures taken of...

MPPR Rollback and Mammography Protections in Consolidated Appropriations Act: A Victory for Patients and Providers
The American College of Radiology (ACR) applauds Congress for including access to imaging care protections for the most sick and injured of Medicare beneficiaries and women seeking mammograms in the Consolidated Appropriations Act. The legislation was passed by Congress and signed into law by the President today (Dec. 18). “The ACR, its member physicians, patients and others have worked with Congress to improve and safeguard patient access to vital imaging care through the protections in this bill. The access to care that these steps will allow can literally mean the difference between life and death for many Americ...
