DICOM SR documents can be thought of as consisting of a document header and a document body. The header metadata attribute values are grouped into modules such as "Patient", "General Study" in PS3.3.
The SR Document Content Module contains the attributes for the root content item that includes the coded report title. The content tree (structured content) of the document body is contained in the nested Content Sequence Items of that module. "Container" content items are part of the Content Sequence. They are structural elements of the SR document body structure. Content items are DICOM SR document nodes within the content tree that are connected through "by-value" relationships (at least for Enhanced SR IODs).
Enhanced SR Information Object Definition (IOD) header relevant for TID 2000 as specified in PS3.3. The contents of any module not covered by this transformation guideline will not be included in the generated CDA document.

DICOM SR Header Modules:
Refer to Section A.6.1 for details.
Patient Module
The patient module specifies the Attributes of the Patient that describe and identify the Patient who is the subject of a diagnostic Study. This Module contains Attributes of the patient that are needed for diagnostic interpretation of the Image and are common for all studies performed on the patient.
Clinical Trial Subject Module
The Clinical Trial Subject Module contains attributes that identify a Patient as a clinical trial Subject. This Annex does not provide mappings for this module since they are outside the scope of this transformation.
General Study Module
The General Study Module specifies the Attributes that describe and identify the Study performed upon the Patient.
Patient Study Module
The Patient Study Module defines the attributes that provide information about the Patient at the time the Study was performed. This Annex does not provide mappings for the module since they would need to be inserted in the content tree.
Clinical Trial Study Module
The Clinical Trial Study Module contains attributes that identify a Study in the context of a clinical trial. This Annex does not provide mappings for this module.
SR Document Series Module
The SR Document Series Module defines the Attributes of the SR Document Series. A Series of SR Documents may contain any number of SR Documents.
Clinical Trial Series Module
The Clinical Trial Series Module contains attributes that identify a Series in the context of a clinical trial. This Annex does not provide mappings for this module.
General Equipment Module
The General Equipment Module specifies the Attributes that identify and describe the piece of equipment that produced a Series of Composite Instances.
SR Document General Module
The SR Document General Module defines the general Attributes of an SR Document Instance. These Attributes identify the SR Document and provide context for the entire document.
SOP Common Module
The SOP Common Module defines the Attributes that are required for proper functioning and identification of the associated SOP Instances.
SR Document Content Module
The Attributes in this Module convey the content of an SR Document. It specifies the root content item and the content tree (refer to Figure A.3-1).
