MQSA meeting to address image quality, breast density
September 14, 2016 -- Should U.S. mammography facilities be meeting higher standards for image quality? And should requirements on breast density be added to the Mammography Quality Standards Act (MQSA)?

Are RTs protected enough during fluoro procedures?
September 12, 2016 -- Over the past 60 years, radiologic technologists (RTs) have tended to follow standard radiation protection protocols. But they're still at greater risk of radiation exposure and ensuing disease, according to a new study published in the American Journal of Roentgenology.
Researchers close in on radiation's cancer-causing mechanisms
September 12, 2016 -- U.K. researchers studying human cancers have identified two characteristic patterns of DNA damage caused by ionizing radiation, enabling doctors to potentially determine which tumors were caused by radiation exposure, according to a study published on September 12 in Nature Communications.
