When children are exposed to head and neck radiation, whether due to cancer treatment or multiple diagnostic CT scans, the result is an increased risk of thyroid cancer for the next 58 years or longer, according to University of Rochester Medical Ce…
A new study shows that a new type of targeted radiation therapy called stereotactic radiation therapy is just as good as surgery for patients aged 75 and older with early-stage lung cancer, according to research presented at the 2010 Chicago Multidi…
Scientists are reporting discovery of the biological secrets that enable plants growing near the Chernobyl Nuclear Power Plant to adapt and flourish in highly radioactive soil — legacy of the 1986 nuclear disaster in the Ukraine. Their study, whi…
Nitric oxide is a toxic pollutant, but the human body also creates it and uses it to attack invading microbes and parasites. A new study by researchers at UC Davis, the Massachusetts Institute of Technology and the Japan Synchrotron Radiation Resear…
CHICAGO — An expert panel convened today at the annual meeting of the Radiological Society of North America (RSNA) to discuss medical imaging appropriateness, ionizing radiation from imaging procedures and efforts under way to curb overutilization…
CHICAGO — The risk of developing radiation-induced cancer from computed tomography (CT) may be lower than previously thought, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).
“Radiat…
OAK BROOK, Ill. — A new study reports that the use of computed tomography (CT) in the nation’s emergency departments is growing exponentially. If the growth trend continues, by 2011, nearly 20 percent of all emergency department (ED) visits may in…
(SACRAMENTO, Calif.) — Patients with head and neck cancer who have never smoked have much better survival rates after radiation therapy than patients with a history of smoking, new research from UC Davis Cancer Center has found.
The study by A…
Multiple testing with the cardiac diagnostic imaging technique of myocardial perfusion imaging is common, and in many patients is associated with a high cumulative estimated radiation dose, according to a study in the November 17 issue of JAMA. The …
A protocol that uses continuous real-time radiation monitoring, low-dose imaging programs and requires physician awareness of radiation dose, significantly reduced radiation exposure during electrophysiology procedures and catheter ablations to diag…
A team of Italian scientists has fired a laser beam into a hunk of glass to create what they believe is an optical analogue of the Hawking radiation that many physicists expect is emitted by black holes. Although the laser experiment superfici…
NEW BRUNSWICK, N.J. — An international team of scientists led by Rutgers University astrophysicists have discovered 10 new massive galaxy clusters from a large, uniform survey of the southern sky. The survey was conducted using a breakthrough te…
