• Michal Guindy. She is the chief responsible for the implementation of the Telepathology system for the Maccabi Health Services (www.maccabi4u.co.il)
• Prof. Tibor Mezei, University of Medicine and Pharmacy of Targu Mures (Romania)([email protected])They are looking for funds and partners to participate in a telepathology international network
Virtual slides repository
Virtual slides repository
• 1.000 virtual slides with diagnosis (anonymous) from HGUCR, Spain will be soon available for free
• http://serendipia.hgcr.sescam.jccm.es/
• Selection of 10.500 virtual slides
• From a proprietary web viewer (Flash based, from Aperio) to a universal viewer, including DICOM, (java based, from Aurora)
• Distributed database
Implementation of SNOMED CT
• Anatomic Pathology supplement (and supporting appendix) published for Trial Implementation
The IHE Anatomic Pathology Technical Committee has published the following supplement (and supporting appendix) to the IHE Anatomic Pathology Technical Framework for Trial Implementation:
• Anatomic Pathology Structured Reports (APSR)• APSR Value Sets AppendixThis profile will be available for testing at subsequent IHE
Connectathons. The documents are available for download at http://www.ihe.net/Technical_Framework. Comments should be submitted to the online forums at http://forums.rsna.org.
Implementation of SNOMED CT
IHE Anatomic Pathology Technical Framework Supplement Anatomic Pathology Structured Reports (APSR) Closed Issues:
• APSR-14 – Gaps in SNOMED CT: It is not straightforward to encode Anatomic Pathology observations and AP ancillary technique observations and their corresponding value sets 360 described in Volume IV (Value Sets for APSR) using SNOMED CT concepts (missing concepts, issues of postcoordination versus precoordination). Therefore these observations and value sets are encoded using a coding system currently being built by the IHE Anatomic Pathology domain (PathLex - OID: 1.3.6.1.4.1.19376.1.8.2.1). PathLex codes are provided with the “Trial Implementation” version of this profile. The 365 terms and expressions of PathLex are being currently mapped to SNOMED CT concepts in collaboration with IHTSDO. Part of this mapping are available in the “Trial Implementation” version and completed over time. Using SNOMED CT as a reference terminology offers promising perspectives
Implementation of SNOMED CT
IHE: Structured Reports Value Sets (1,840 possible values for observations)
HGUCR: 3,000 pathology diagnosis codes mapped to SNOMED CT
Postcoordination needed in 12% (3 conceptID needed only rarely)
