Background: The research project REPO (Radiology Ehealth PlatfOrm) was started in 2017 with the goal to “enable cross-enterprise collaboration in radiology using the Austrian eHealth infrastructure”.

Objectives: The objective of this paper was to provide an overview of the radiology IT environment – actors, use cases and technology.

Methods: We conducted semi-structured expert interviews with radiologists and hospital operators and we statistically analyzed the client database of our research project partner.

Results: Interviews led to a list of use cases where cross-enterprise collaboration in radiology takes place and the data analysis provided insights on the systems, networks and standards in place.

Conclusion: The Austrian IT infrastructure in radiology is a heterogeneous naturally grown environment. Future developments should be based on internationally accorded standards and on integration profiles provided by Integrating the Healthcare Enterprise (IHE).
