Soaring Numbers of CT Scans Performed on Children at Hospitals

The number of children receiving emergency room CT scans has soared in recent years, raising concerns about the health risks of exposing kids to large amounts of radiation.

As the Associated Press reports, a new study found that the number of the scans leapt from 330,000 in 1995 to 1.65 million in 2008, a fivefold rise, even though there was no measurable  increase in children’s ER visits. But while only 1 percent of children’s ER visits included a CT scan in 1995, the figure was up to 6 percent in 2008.

Although the CT, or computed tomography, scan is prized for providing detailed cross-sectional pictures of the body, its potentially large doses of radiation can raise the risk of cancer. What’s more, abdominal CT scans, which deliver up to seven times more radiation than head scans, account for a growing proportion of the procedures.

According to the study, which was published in the journal Radiology, children are especially vulnerable to the dangers of radiation. That’s because they have smaller organs more susceptible to large doses. In addition, they face more years of medical procedures that could build up their cumulative exposure to radiation.

Perhaps even more worrisome, numerous accidents have been reported in recent years in which patients were badly harmed by accidental radiation overdoses from medical imaging equipment.

Previous studies have demonstrated that it’s not just children who are being exposed to CT scans. The overall number of the scans jumped from 2.7 million in 1995 to 16.2 million in 2007.

One factor driving the use of the CT scans may be a concern about legal liability. “If you send a kid home [without a CT scan] and it turns out you missed an abnormality, not many juries are going to be sympathetic,” said the study’s lead researcher, Dr. David Larson of Cincinnati Children’s Hospital Medical Center.
