[Standardization for Promoting Interoperability of Healthcare Data: The Progression of the Korean Society of Radiology].

In 2023, the Korean Core Data for Interoperability (KR-CDI), comprising 77 elements, was established as a compliance item for healthcare data exchange in Korea to promote patient-centered medical information exchange and reestablish national interoperability in healthcare standardization. Radiologic examinations are in the core classification of diagnostic imaging tests, and the examination name, results, and image data must be exchanged based on standard codes of terminology and transfer. Accordingly, the Korean Society of Radiology has formed a standardization committee that maps radiologic examination names to international standard codes, such as LOINC and SNOMED CT. Additionally, we propose a pilot project for the standardization and exchange of DICOM images and plan a project to map the terms of the Conclusion sections of diagnostic reports to standard codes. The Korean Society of Radiology is actively participating in these efforts.
