Erratum to: Letter to the editor: “Utilization of CT and MRI scanning in Taiwan, 2000–2017” (Insights into Imaging, (2023), 14, 1, (83), 10.1186/s13244-023-01420-x)

Dear Editor in Chief,
We thank Li et al. [1] for their interest in our study [2]. We really appreciate the feedback and guidance for future work.
First, with regards to using the entire population of Taiwan as the denominator for calculating utilization rates, this is actually in accordance with OECD data, which also uses the entire population as the denominator in the
formula to calculate utilization rates. Terefore, the comparison is apples-to-apples.
Accordingly, based on what has been conveyed in Table 1, the source of the data in Table 1 for Taiwan has been classifed by hospital or medical urban center, this
should not be misconstrued to depict the whole population of Taiwan. In addition, we would be unable to utilize the number of yearly users of ED services in Taiwan, as records only note CT usage and are not adjusted to the individual level.
