In the Region Vastra Gotaland (VGR), Sweden, sharing of data from 4 PACS system has been done through the Radiology Information Infrastructure that where deployed in 2007, and during 2008 and 2009 also including the information obtained from three different RIS systems installed in the region. The RIS information stored in the Radiology Information Infrastructure is Structured Reports (SR) objects that derivatives from the regional information model. In practice, the Enterprise solution now offers new ways of social collaboration through information sharing within a region.
Interoperability was developed according to the IHE mission, i.e. applying standards such as digital imaging and communication in medicine (DICOM) and Health Level 7 (HL7) to address specific
clinical communication needs and support optimal patient care.
Applying standards and information has shown to be suitable for interoperability, but not appropriate for implementing social collaboration i.e. first and second opinion, as there is no user services related to the standards. The need for social interaction leads to a common negotiated interface and in contrary with interoperability the approach will be a common defined semantic model.
Radiology informatics is the glue between the technical standards, information models,semantics, social ruleworks and regulations used within radiology and their customers to share information and services.
