Hazards of CT scans overstated

Concerns over possible radiation effects of CT scans detailed in a report yesterday in the New England Journal of Medicine should not scare people away from getting medically needed CT scans, as the scans play a critical role in saving the lives of thousands of people every day, according to an official with the American Association of Physicists in Medicine (AAPM).

Skin injuries to patients can be avoided when radiation dose is monitored

Maximum radiation skin dose during coronary angioplasty can be accurately determined by monitoring the total entrance skin radiation dose as the patient is being examined and dividing that number in half according to a recent study conducted by researchers at Tohoku University in Sendai, Japan.

New device delivers radiation therapy to specific tumor sites

Physicians at the Rebecca and John Moores UCSD Cancer Center will present the initial outcomes of their use of a new device that delivers radiation therapy to a specific tumor site at the annual meeting of the Radiological Society of North America (RSNA), November 25-30, 2007, in Chicago, Illinois.

New insights into cataracts

Using the tools and techniques of soft condensed matter physics, a research team in Switzerland has demonstrated that a finely tuned balance of attractions between proteins keeps the lens of the eye transparent, and that even a small change in this balance can cause proteins to aggregate and de-mix.

Children would need different medical care in wake of dirty bomb

If terrorists were to attack with a dirty bomb, medical authorities should be prepared to treat children differently than adults because their developing bodies would absorb and respond to the radiation exposure in distinct ways, according to a new study from the University of Rochester Medical Center.
