Top 5 trends from RSNA 2013; 'overdiagnosis' in CT lung cancer screening

Dear AuntMinnie Member,

The booths have been broken down and the halls of McCormick Place are now empty. Radiology's showcase conference is just a memory, but there are some important insights we can gain by looking back at RSNA 2013.

We've identified five of the top trends from the meeting in a new article in our RADCast @ RSNA special section. The article profiles the five dominant themes that our editors felt defined the show.

Interestingly, three of the five pertain to economic issues: the future of radiology, the decline in imaging procedure volume, and concerns over job security for radiologists in the future. All three issues are inextricably linked, and taken together they underline the uncertainty facing both the RSNA show and radiology.

'Overdiagnosis' in CT lung cancer screening

Well, that didn't take long. Radiology's excitement over the prospects of CT lung cancer screening this week got a bucket of cold water to the face, in the form of a new study in JAMA Internal Medicine pointing to the potential for "overdiagnosis" of cancer.

Researchers from Duke University analyzed data from the National Lung Screening Trial -- the study that demonstrated CT screening's efficacy in the first place -- and found that some 18% of cancers detected in the study would never have progressed to threaten the patient.

The findings echo the debate that's raged in mammography for years regarding overdiagnosis. Proponents of CT lung cancer screening would do well to examine the arguments of their brethren in breast imaging in crafting a response to the new findings.
