Despite radiation exposure and fracture risk, pricey QCT bone density scans are rising in popularity

The increase may be an unintended result of a cut in DXA reimbursement rates in 2007, a MedPage Today article suggests. 

Experts highlight 'suboptimal' rates of CMS-required shared decision making encounters prior to LDCT

These findings underscore the need for better implementation of shared decision-making (SDM) models, as well as more thorough counseling documentation, as low-dose CT (LDCT) lung screen coverage is dependent on these factors, experts suggested.
