Total daily thoracic CT utilization. At the height of the pandemic, there was greater than 100% decrease in overall daily chest CT utilization. The decline in utilization was inversely related to the number of hospitalized COVID-19 cases, and it increased as fewer patients were hospitalized. Dashed lines represent polynomial lines of best fit.
