Hospital-based procedures drive CT procedure volume growth

CT procedure volumes increased 9.1% from 2022 to 2023, according to IMV’s recently published 2023 CT Market Outlook Report. While both hospital and nonhospital CT procedure volumes increased, hospital volumes increased year-over-year by almost 10%, while nonhospital volumes increased just over 6%.

Overall 9.1%
Hospital 9.8%
Nonhospital 6.4%

Looking ahead into 2024, 72% of CT sites surveyed anticipate that their 2024 CT procedures will increase compared to 2023, while 23% expect them to stay the same and just 1% of sites anticipate a decrease. One likely cause of the increase – with 60% of survey respondents rating the likelihood at 4 or 5 out of 5 -- is due to some procedures shifting from other imaging modalities to CT, according to the report.

When it comes to staff that will handle these potentially increased volumes, on average sites surveyed reported seven technologists per site (with a range of three technologists in independent imaging centers to 17 in hospitals with more than 400 beds).

Overall, the report found that in 2023, an average of two CT technologists are involved with performing and preparing patients for CT exams on each scanner in their facility. This varies across sites, with 34% of survey respondents reporting one technologist performing these duties, 48% of sites reporting two, and 17% of sites reporting three or more technologists to prepare patients for CT exams on each scanner.

Other key findings from the report include the following:

  • In 2023, the top priority for CT departments has been to "improve patient satisfaction with their CT experience," with 92% of respondents rating this as a 4 or 5 out of 5.
  • As of this report, GE has 32% of the CT installed base market share, followed by Siemens (32%), Canon (18%), Philips (12%), and Fujifilm (5%).

CT procedure volumes have shown strong growth over the last few years, and as volumes continue to increase, the more efficient sites with available technologist capacity are in the best position to realize the benefits from the increased volumes.
