Topic: Validation Problem with DICOM SOP Class

Hello, i am currently extracting data from an pacs to clarify which patient has got some image diagnostics. Therefore I am implementing ImagingStudy . While I am validating my implementation i got this error. Is this a real problem, or just some issue about a valueset which is not available by default:
ValueSet http://dicom.nema.org/medical/dicom/current/output/chtml/part16/sect_CID_29.html not found by validator
ValueSet http://dicom.nema.org/medical/dicom/current/output/chtml/part04/sect_B.5.html#table_B.5-1 not found by validator

The second error belongs to the following Instance

{
                    "uid": "1.2.840.113619.2.1.1.2703111462.474.1106049360.738",
                    "sopClass": {
                        "system": "urn:ietf:rfc:3986",
                        "version": "01",
                        "code": "urn:oid:1.2.840.10008.5.1.4.1.1.4",
                        "userSelected": false
                    },
                    "number": 1
                } ```

@Jan Maluche I suspect this goes back to the fact that DICOM's "official" url for the modality and SOP class codes doesn't actually resolve to a FHIR ValueSet.

John Moehrke (Oct 17 2020 at 14:09):

@Jan Maluche is this with current build of FHIR core, or previous (like R4)? We have updated FHIR core in the current build to pull directly from the valueSets that dicom publishes. Prior versions of FHIR use a mix of copies and such.

yes validation of dicom value sets should all work now, but that doesn't look like teh R4 specified URL?

Sorry for the late response. I used Version 4.0.1 in the validator @John Moehrke
