In this large retrospective cohort from 6 integrated health care systems over 15 years, the number of imaging tests performed were 1.2 / person / year, of which ~1/3 were advanced diagnostic imaging (e.g. CT, MRI, USG, nuclear). CT use increased 8%/year, MRI increased 10% / year, and USG 4% / year. Mean per capita radiation dose doubled. Although this study did not evaluate appropriateness, some of this exposure was likely unnecessary, and continues to escalate over time (abstract)
