Indeed. I would also like to see that British study that claims a link between CTs and leukemia – I smell selection bias. It is however true that a CT does imply a significant radiation dose.

This article is especially frustrating in that the authors seem to be doctors in the appropriate fields. I assume they just went too far in dumbing down the matter, which together with their source-less references to a dazzling amount of numbers and studies ends up obscuring their main point: A culture of using the “best” medical tool available instead of the “appropriate” tool can have adverse health effects, and has to stop.

All in all, there is a reason this article was filed under Opinions, not Science.
