C.17.3.2.4 Content Sequence and Relationship Type

Content Sequence (0040,A730) provides the hierarchical structuring of the Content Tree (see Section C.17.3.1) by recursively nesting Content Items. A parent (or source) Content Item has an explicit relationship to each child (or target) Content Item, conveyed by Relationship Type (0040,A010).

Table C.17.3-8 describes the Relationship Types between Source Content Items and the Target Content Items.

Table C.17.3-8. Relationship Type Definitions

Relationship Type

Description

Definition and Example

CONTAINS

Contains

Source Item contains Target Content Item.

E.g., CONTAINER "History" {CONTAINS: TEXT "mother had breast cancer", CONTAINS: IMAGE}

HAS OBS CONTEXT

Has Observation Context

Target Content Items shall convey any specialization of Observation Context needed for unambiguous documentation of the Source Content Item.

E.g., CONTAINER "Report" {HAS OBS CONTEXT: PNAME "Recording Observer" = "Smith^John^^Dr^"}

HAS CONCEPT MOD

Has Concept Modifier

Used to qualify or describe the Concept Name of the Source Content Item, such as to create a post-coordinated description of a concept, or to further describe a concept.

E.g., CODE "Chest X-Ray" {HAS CONCEPT MOD: CODE "View = PA and Lateral"}

E.g., CODE "Breast" {HAS CONCEPT MOD: TEXT "French Translation" = " Sein "}

E.g., CODE "2VCXRPALAT" {HAS CONCEPT MOD: TEXT "Further Explanation" = "Chest X-Ray, Two Views, Postero-anterior and Lateral"}

HAS PROPERTIES

Has Properties

Description of properties of the Source Content Item.

E.g., CODE "Mass" {HAS PROPERTIES: CODE "anatomic location", HAS PROPERTIES: CODE "diameter", HAS PROPERTIES: CODE "margin", …}.

HAS ACQ CONTEXT

Has Acquisition Context

The Target Content Item describes the conditions present during data acquisition of the Source Content Item.

E.g., IMAGE {HAS ACQ CONTEXT: CODE "contrast agent", HAS ACQ CONTEXT: CODE "position of imaging subject", …}.

INFERRED FROM

Inferred From

Source Content Item conveys a measurement or other inference made from the Target Content Items. Denotes the supporting evidence for a measurement or judgment.

E.g., CODE "Malignancy" {INFERRED FROM: CODE "Mass", INFERRED FROM: CODE "Lymphadenopathy", …}.

E.g., NUM: "BPD" = "5mm" {INFERRED FROM: SCOORD}.

SELECTED FROM

Selected From

Source Content Item conveys spatial or temporal coordinates selected from the Target Content Item(s).

E.g., SCOORD "POLYLINE1,1 5,10 5,10 1,10 1,1" {SELECTED FROM: IMAGE}.

E.g., TCOORD "SEGMENT 60-200mS" {SELECTED FROM: WAVEFORM}.
