A new study from the Harvey L. Neiman Health Policy Institute found that unnecessary imaging studies in Original Medicare are associated with up to 129 kT of CO2 emissions—the same as would be produced from powering a town of over 70,000 people for a year. The research, published in the Journal of the American College of Radiology, demonstrates the opportunity for the field of radiology to meaningfully reduce its environmental footprint.

Scientists have confirmed a neurobiochemical link between dopamine and cognitive flexibility, according to new research published in the March issue of The Journal of Nuclear Medicine. PET imaging shows that the brain increases dopamine production when completing cognitively demanding tasks, and that the more dopamine released, the more efficiently the tasks are completed.
