Major advances have been made in the development of Alzheimers disease (AD) biomarkers in the last two decades, with models of the temporal evolution of AD biomarkers offering the possibility of staging the course of the disease. Despite the achievements in this field, a major unmet need is the standardization of quantitative metrics for AD imaging biomarkers, according to an article published in the May issue of Radiology.

U.S. Senators Richard Burr (R-N.C.) and Tom Coburn (R-Okla.) have introduced the Promoting Accountability, Transparency, Innovation, Efficiency and Timeliness at FDA (PATIENTS FDA) Act, a bill to help make sure that the FDA fulfills its mission to ensure that patients have access to cutting-edge, life-saving drugs and devices as quickly as possible.

Overeating, drug addiction relapses and impulsive sexual behavior may have a deeper cause than a simple lack of will power.

Because young children are more sensitive to radiation than adults, pediatric nuclear medicine providers need to have at least a basic understanding of radiation risk and dosimetry, as well as know how to effectively communicate this information to patients and their families, according to an article published in the March issue of the Journal of Nuclear Medicine Technology.

Carestream Health has received FDA clearance for its Carestream DRX-Revolution mobile x-ray system, and is now accepting orders from U.S. healthcare facilities.

The American College of Radiology (ACR) has named Eric S. Perlman, MD, the chief medical officer (CMO) of ACR Image Metrix, a contract research organization and for-profit subsidiary of the ACR.

Are some surgeons merely paying lip service to collaborative, multidisciplinary decision making? Radiation oncologists often were excluded from early steps in the breast cancer treatment decision-making process, leaving some patients uninformed of all of their treatment options and potentially leading to more mastectomies over breast-conserving therapy, according to a study published in this month's International Journal of Radiation OncologyBiologyPhysics.
