I am a board certified radiologist and a partner in a large practice - where I do diagnostic work in addition to IR. I've been in practice for nearly 10 years - and judging by your handle info, I've been in practice longer than you (for all I know you're just a resident). You gotta do better than "most radiologists I've talked to..." or "my BFFs in IM and ER told me something else"
The article I posted quotes 2 other peer reviewed journal articles including one from JACR.
Here's another article from AJR:
Inpatient imaging utilization: trends of the past decade. - PubMed - NCBI
"CONCLUSION: After decades of continued rise, imaging utilization for inpatients significantly decreased by most measures between FY 2009 and FY 2012. Future studies to evaluate the contribution of various factors to this decline, including efforts to reduce inappropriate use of imaging and concerns about potential harms of radiation exposure, may be helpful in optimizing imaging utilization and resource planning."
Yes, the articles are 3-4 years old, but they are the latest data available as it does take a few year to compile and analyze data. Any physician who knows anything about utilization data, whether it's in the OR or in radiology, knows that is always the case.
Please just stop. It's great that you're busy. It's good for your practice -- or if you're a resident -- for your training. But the facts are the facts.
