August 2014 DICOM Chengdu Workshop Charles Kahn DICOM and the Future of Medicine2
An Example
Radiology Reporting
An international effort• Led by the Radiological Society of North America (RSNA)• Soon to include the European Society of Radiology (ESR)
Goals• Improve the communication of radiology procedures• Allow “data mining” of radiology results
August 2014 DICOM Chengdu Workshop Charles Kahn DICOM and the Future of Medicine3
Radiology Reporting
• Library of “best practice” templates• RadReport.org
• Standard for report templates• Integrating the Healthcare Enterprise (IHE)• “Management of Radiology Report
Templates” (MRRT) profile

Why Templates?
• Reduce variability of reports• Improve completeness• Encourage best practices
• Improve interoperability • Support automation of report production• Support validation of report content• Promote data extraction

New “Work Item”• Proposed to DICOM Standards Committee
• Assigned to Work Group 8 (Structured Reporting)
– Harry Solomon (GE Healthcare), co-chair– Charles Kahn (ACR), co-chair
August 2014 DICOM Chengdu Workshop Charles Kahn DICOM and the Future of Medicine12
Working Group 8
DICOM Supplement 155• Defines how radiology reports are exported
into HL7 Clinical Document Architecture (CDA)
• CDA provides a universal format for clinical results
– Integrates radiology results with entire health record– Allows “data mining” for research and quality
improvement
August 2014 DICOM Chengdu Workshop Charles Kahn DICOM and the Future of Medicine13
Why do physicians work on DICOM?• Technical expertise• Advocacy and communication with physician
communities • Contribution to international effort
August 2014 DICOM Chengdu Workshop Charles Kahn DICOM and the Future of Medicine14
How can DICOM improve medical practice?
• Standards foster competition to create better products
• DICOM helps advance the worldwide adoption of new medical imaging technology
