[Source: ScienceDaily] - Computed tomography (CT) scans are responsible for more than two thirds of the total radiation dose associated with medical imaging exams. However, a newly adapted low-dose technique called adaptive statistical iterative reconstruction (ASIR) may enable radiologists to reduce patient radiation resulting from CT up to 65 percent, according to a study published in the September issue of the American Journal of Roentgenology (AJR).
Iterative reconstruction is a technique that allows radiologists to reduce the noise in an image and improve image quality (like adjusting a TV antenna to make a "fuzzy" image sharper) while significantly reducing the radiation dose.
Now available: “Arizona’s Bioscience Roadmap 2014-2025: Advancing the Biosciences and Improving Health Outcomes,” is now available along with its supplement, “Summary of Goals, Strategies, and Potential Actions.” An overview by Walter Plosila, Ph.D., Battelle senior advisor, is also available. The updated Roadmap provides a long-term strategy for Arizona to achieve bioscience success over the next decade.
