Brain research: A picture says more than a thousand words
Today, modern technology makes it possible to visualize molecular memory processes within the brain and to look into the inside of nerve cells. Therefore, 'imaging techniques' are essential for understanding memory formation and cognition and the development of new therapies against brain diseases. The German Center for Neurodegenerative Diseases (DZNE) is now focusing its nationwide expertise in the field under the umbrella of the 'National Neuroimaging Network'. Magdeburg neuroscientist Emrah Düzel is coordinating these efforts. (2015-12-18)

Nonphysician providers rarely interpret diagnostic imaging -- except radiography, fluoroscopy
Although Medicare claims data confirm the increasing role of nonphysician providers in imaging-guided procedures across the United States, according to ARRS' American Journal of Roentgenology, nurse practitioners and physician assistants still rarely render diagnostic imaging services, compared with the overall number of diagnostic imaging interpretations. When nonphysician providers do interpret diagnostic imaging, though, it is overwhelmingly radiography and fluoroscopy. Whereas state-to-state variation exists, these rates are also uniformly low, due to scope-of-practice laws and regulations. (2019-09-13)
