Radiation exposure

  • Even in health care systems in which doctors do not bill for each test they administer, the use of diagnostic imaging like CT and PET scans has soared, as has patients' radiation exposure, a new study has found.
  • (New York Times)
  • Money may not be the driving force behind increased medical imaging, according to new research that finds imaging, even when provided through HMOs which do not use a fee-for-service model, has increased significantly over the past 15 years.
  • (Huffington Post)
  • Newswise — Concern about overexposure to radiation due to excessive use of medical imaging has come to the fore in recent years.
  • (Newswise)
  • The number of Americans undergoing advanced imaging tests has skyrocketed, increasing their exposure to radiation that may result in cancer later in life, a study found.
  • (Bloomberg)
  • San Francisco — Improved medical imaging tests give doctors a better look inside patients bodies and help them make earlier and more accurate diagnoses, but the radiation exposure can sometimes outweigh the benefits of these expensive tests.
  • (WRAL)
  • Molecular imaging is effective for providing information about disease processes. Today's hybrid imaging systems have additional computed tomography (CT) technology on board for alignment and imaging structures.
  • (Med India)
  • June 12, 2012 -- Another major study is pointing to significant increases in radiation exposure from the growing use of medical imaging tests such as CT scans.
  • (WebMD)
  • In April, the Defense Advanced Research Projects Agency issued a call for the development of robots to deal with stricken nuclear reactors to reduce human exposure to deadly radiation.
  • (Science Daily)
  • Hoppe, a Marquette graduate student. Their study estimated radiation exposure to 29 organs, including skin, eye lens, heart, and the brain—using complex mathematical models that represent the shape and tissue density of human bodies and organs.
