My favorite source for imaging procedure utilization estimates for the U.S. is the data vendor IMV Medical Information Division, Inc. They offer Benchmark Reports for different imaging modalities; the latest one out is for positron emission tomography (PET) scanning. I like it that they have data from hospital and non-hospital sites and that some comparative historical data are given.
Here is an example:
- 1,616,900 total clinical PET scans (2014)
- Comparable data are given for each year from 2005 to 2013
- Interestingly, the inflection point was 2011, when the clinical PET utilization topped out at 1,853,700
- Anybody have thoughts as to why clinical PET utilization, after rising steadily and consistently from 2005 to 2011 is now headed down?
