Table 10-5, Table 10-6, Table 10-7 and Table 10-7b describe the Attributes for identifying the general region of the Patient anatomy examined using coded terminology, as well as the principal structure(s) within that region that is the target of the current SOP Instance. The only differences between the Macros are the Type and Number of Items of the Anatomic Region Sequence (0008,2218) Attribute. Table 10-8 describe the Attributes for the coding of the principal structure only.
The invocation of these Macros may specify Baseline or Defined CIDs for the Anatomic Region Sequence (0008,2218), the Anatomic Region Modifier Sequence (0008,2220), and/or the Primary Anatomic Structure Sequence (0008,2228).
The general region of the body (e.g., the anatomic region, organ, or body cavity being examined) is identified by the Anatomic Region Sequence (0008,2218). Characteristics of the anatomic region being examined, such as sub-region (e.g., medial, lateral, superior, inferior, lobe, quadrant) and laterality (e.g., right, left, both), may be refined by the Anatomic Region Modifier Sequence (0008,2220).
These Attributes allow the specification of the information encoded by the Body Part Examined (0018,0015) in the General Series Module in a more robust, consistent way.
The specific anatomic structures of interest within the image (e.g., a particular artery within the anatomic region) is identified by the Primary Anatomic Structure Sequence (0008,2228). Characteristics of the anatomic structure, such as its location (e.g., subcapsular, peripheral, central), configuration (e.g., distended, contracted), and laterality (e.g., right, left, both), and so on, may be refined by the Primary Anatomic Structure Modifier Sequence (0008,2230).
Laterality is often encoded in a separate Attribute, Image Laterality (0020,0062) or Frame Laterality (0020,9072), rather than in Anatomic Region Modifier Sequence (0008,2220) or Primary Anatomic Structure Modifier Sequence (0008,2230). The correspondence between the values is as follows:
The codes illustrated are from CID 244 “Laterality”.
Whether or not various anatomical structures may be paired or unpaired (have laterality) is illustrated in Table L-5 “Pairedness of Anatomic Concepts” in PS3.16.
