Dear Digital X-Ray Insider,

News flash: Chest radiography has been largely immune to the ebb and flow of imaging utilization that's driven up Medicare costs over the past decade.

That's according to a new study presented at the RSNA 2012 meeting by utilization experts Dr. David C. Levin and Dr. Vijay Rao of Thomas Jefferson University. They studied chest x-ray use in Medicare from 2000 to 2010, and found that utilization rose at largely the same pace as growth in the general patient population.

The results aren't particularly surprising, as most of the utilization growth in imaging has been found in high-tech modalities such as CT and MRI. But the study does offer evidence that changes in self-referral patterns have been driving at least some of the rise -- and subsequent fall -- in Medicare reimbursement patterns.

In other news from RSNA 2012, researchers from Norway found that chest radiography probably ought to be retired in favor of CT, if cost is no object. They used an iterative reconstruction protocol to bring the radiation dose of 320-detector-row CT down to only twice that of a chest x-ray. Learn more by clicking here.
