DICOM PS3.17 2022c - Explanatory Information

YYYY.3.5 Additional Data Elements

The Inventory IOD, like all DICOM IODs, may be extended by the addition of optional Attributes that do not impact the semantics of the basic IOD. This is denoted Standard Extended Conformance (see Section 3.11 “DICOM Conformance” in PS3.2).

While the IOD identifies many optional Attributes that might be managed in a repository database, the creator of an Inventory is allowed to use such Standard Extended Conformance to include any additional data elements that it manages. This may support additional use cases for the Inventory SOP Instances, or may provide direct database record keys in Private Data Elements for implementation-specific processing.


For example, the repository database may support at the Instance level the Content Label and Content Description to support queries against Presentation States in accordance with the [IHE RAD TF-1] Consistent Presentation of Images (CPI) Profile, or the Template ID and Concept Name Code Sequence to support queries against Structured Report SOP Instances in accordance with the [IHE RAD TF-1] Evidence Documents (ED) Profile.
