Volumes are drawn from different years and definitions, so the ranking serves as a benchmark.

The annual X-Ray scan volume includes 320M dental scans. The average out-of-pocket cost for a dental scan is $66[12], and the price range is $25 – $750[13].

Avg. out-of-pocket cost and price range are directional benchmarks.
