CT scanning, among other imaging technologies, have revolutionized how we diagnose and monitor many diseases. However, ever expanding indications and uses for the technology has led to a dramatic increase in the number of scans performed every year, which has led some to wonder if it is now being overused and if the risk from exposure to radiation is worth the benefits. This story reports on a review article published in this week’s New England Journal of Medicine on the state of the extent of the radiation exposure issue.
The story adequately describes the availability and novelty of CT scanning. It does not engage in disease mongering. The story does a good job of describing the risk from radiation exposure. The story could have mentioned other potential harm of overuse of the CT scans, such as overdiagnosis, incidental findings and the dangers of false-positive or false-negative results.
The story does not adequately describe the strength of the available evidence, nor does the story mention the cost of the scans, an important concern given how widespread and common they are. Finally, the story does not quantify the harms of radiation exposure. How many additional cases of cancer could be explained by the increase in CT scanning?

The story does a good job of describing the risk from radiation exposure. The story could have mentioned other potential harm of overuse of the CT scans, such as overdiagnosis, incidental findings and the dangers of false-positive or false-negative results.
The story does not discuss the strength of the available evidence that CT scans raise the risk of cancer. The story refers to the article in this week’s New England Journal of Medicine, which is just a review article.
The story quotes an independent expert in addition to the lead author of the new article.
The story mentions conventional X-rays, ultrasound and MRI as alternative technologies to CT scanning. The story could have provide more content on the pros and cons of the different approaches and could have mentioned that not all cases need to have imaging.
By describing the CT scans as "routine", the story implies that CT scans are widely available.
The story indicates that CT scanning is not a new idea but that the utilization of the test has increased dramatically.
The reporter covered the conference where the paper was presented. He also interviewed an independent expert, so it’s safe to assume the story did not rely solely or largely on a news release.
Systematic, Criteria-Driven
Monday at #ADA2021, an infectious disease epidemiologist, a journalist, and a researcher shared perspectives on communication of risk in the era of COVID-19: http://ow.ly/ROfR30rMeE7 @AstleyCM @garyschwitzer @berthahidalgo @ADA_DiabetesPro
Shoutouts to @susan_bewley @drkevinknopf @MichaelBaum11 in this call for more than fawning coverage from press releases for these kinds of stories.
Also, linked history inside goes back 5 years just on Grail apparently trying to become Holy Grail. https://twitter.com/garyschwitzer/status/1408849696416841731

There has been a recent burst of attention to troubles with many comments left on science and science news/communication websites. Read “Online science comments: trolls, trash and treasure.”
The authors of the Retraction Watch comments policy urge commenters:
We”re also concerned about anonymous comments. We ask that all commenters leave their full name and provide an actual email address in case we feel we need to contact them. We may delete any comment left by someone who does not leave their name and a legitimate email address.
