A new study estimates nearly 5,000 cases of cancer are directly related to exposure to radiation from pediatric CT scans, according to NBC News.

Researchers at the University of California Davis studied the trends in pediatric CT scans to estimate future cancer cases. They found the number of young children who underwent CT more than doubled from 1996 to 2005 before they started to decline.

According to their estimates, 4,800 cases of cancer could be attributed to the 4,000,000 CT scans performed each year.

The risk was higher for younger patients, girls, kids who had scans of their abdomen and spine and those who have multiple CT scans over their life.

Doctors say they are aware of the risk and try to use other scanning methods if possible, but that may not always be the case.

"There are still situations where the CAT scan is really the best choice, because it is so quick and can be done so rapidly," according to Dr. James Fortenberry of Children's Healthcare of Atlanta. "When that's the case, when we make that choice, we're choosing to use a lower dose to minimize any potential radiation exposure."
