Radiologists build radiation dose registry just for kids
By Eric Barnes
With all eyes on pediatric radiation dose these days, researchers from six children's hospitals in the U.S. are collaborating to build the first pediatric CT dose index registry. The group is beginning with a study to set pediatric abdominal CT diagnostic reference dose levels based on patient size.

FDA targets vendors in push to trim pediatric radiation dose
By Brian Casey, Eric Barnes
The U.S. Food and Drug Administration has raised the ante in its drive to reduce pediatric radiation dose, launching a new program that will require manufacturers to consider the safety of children when designing new x-ray imaging devices. Devices that do not comply with the program may have to carry warning labels advising against their use in children.

Radiologists could be key in identifying signs of elder abuse
By Rosemary Frei
A radiologist-led team from Toronto has identified a gestalt of injuries and surrounding social context common to most cases of physical abuse of the elderly. The group believes this could be a guide to identifying victims of elder abuse, much as a pediatric radiologist defined the signs of shaken-baby syndrome in the 1940s.

Low-dose CT's bright future, troubled present
By Eric Barnes
The task at hand in CT radiation dose reduction is pretty straightforward: Record the dose, establish best practices for using it, and then use the right dose for every scan. But in reality these goals are so complex as to be nearly impossible, said Dr. R. Paul Guillerman of Texas Children's Hospital in Houston.

Antioxidant formula halves DNA damage from CT
By Eric Barnes
A new study in Radiology has found that ingesting a commercially available combination of antioxidants reduces DNA damage by more than half compared to results obtained without antioxidant protection after irradiation with doses comparable to a CT angiography exam.

Oral antioxidants could prevent DNA damage from radiation
By Rosemary Frei
Canadian researchers plan to start clinical trials soon of an oral antioxidant cocktail designed to prevent radiation-induced DNA damage from medical imaging scans. The trial follows tests they've already conduct in humans -- more specifically, themselves.
