C.11.28.2 Referenced Structured Content Sequence

A volume annotation provides graphics and text to include in the presentation, but doesn't provide any context for the annotation. Context may be provided through an optional reference to a Structured Report concept. The structured concept could be in the form of a finding concept code or measurement from the Structured Report. It is an application-specific decision on whether to use this reference and how to make use of the information it provides.
