Content Item Descriptions

Anatomic Identifier An identifier of an anatomic feature when a multiplicity of features of that type may be present, such as “Rib 1”, “Rib 2” or thoracic vertebrae “T1” or “T2”.
Rendering Intent This content item constrains the SCP receiving the Chest CAD SR IOD in its use of the contents of this template and its target content items. Chest CAD devices may opt to use data marked “Not for Presentation” or “Presentation Optional” as input to subsequent chest CAD processing steps. Refer to PS 3.4 section on Structured Reporting Storage SOP Classes for SCU and SCP Behavior.
CAD Operating Point Additional information to use when Rendering Intent is “Presentation Optional”. A CAD Operating Point of zero is not sent, and is encoded as a Rendering Intent of “Presentation Required”. See PS 3.4 section on Structured Reporting Storage SOP Classes for SCU and SCP Behavior and PS 3.17 annex on Mammography.
Certainty of Finding The certainty of the CAD device that the finding detected and classified by the Single Image Finding CODE specified is in fact that type of finding.
