FYI,
We were asked by a journalist to respond and we prepared some comments last week and shared with the journalist. Our chairman was involved in preparing the comments.

Hope AAPM does come out with a response Mahesh.

Be prepared for the mainstream press to get hold of this and sensationalize it.

My observations:

Is the increase in spontaneous abortion due to the CT scans or the reasons the patients got the CT scans to begin with? The authors acknowledge that the majority of the cohort had diabetes, hypertension, obesity or were smokers. (Smokers and pregnant???)

The results also make the statement, “The risk observed with head CT was not consistently lower than with CT of the abdomen, pelvis, or lower spine.”  How is that possible unless the increased rate of spontaneous abortion was due to some factor other than X-ray exposure?
