First, when we're talking about imaging overuse we're generally talking about injuries and back/joint paint.

But it's also probably not true that we screen less aggressively than Europe. For instance, I think we start breast cancer screening earlier than Europe. There are European countries with better rates of colorectal screening, but that's a patient compliance issue as much as anything else (and 10 years from now standard of care is unlikely to be imaging-based for that screening for most pts).
