Dr. Len Lichtenfeld, deputy chief medical officer for the American Cancer Society in Atlanta, agreed that the issue is in the amount of CT scans used on patients.
"We as a nation are in love with technology," said Lichtenfeld. "We're going in the complete opposite direction where I think we should go. We need to take a step back, respect technology, but understand the limitations of technology and not assume everything must be used all the time."
"That being said, if a person needs a CT scan, they can have a significant impact on improving health and guiding further treatment," he added.
Schultz said his patients sometimes worry about the radiation dose, and try to opt out.
"I always try to put it in perspective for the patient," said Schultz. "If it's a serious issue, we need to educate them on the small risk and possible benefit of the scan."
"Sometimes patients are worried about something that will kill them in 40 years," said Schultz. "I'm worried more about something that will kill them in 48 hours."
Brenner encourages patients to ask the physician why they need this CT scan, what is to be learned and whether it will help with treatment.
