TID 4121 Colon CAD Findings Summary Template

The contents of this template describe the findings and aggregate features that the colon CAD device detected for the colon evidence presented. This template forms the colon CAD results sub-tree of the Colon CAD Document Root (TID 4120). The data from which the details are inferred are expressed in the Composite Features (see TID 4125) and/or Single Image Findings (see TID 4127), of which there may be several.

The sub-tree headed by this template is illustrated in the figure entitled “Example of CAD Processing and Findings Summary sub-tree of Colon CAD SR Content Tree” in the “Colon CAD” Annex of PS 3.17.

Content Item Descriptions

CAD Processing and Findings Summary This code value is used to express if and why the Colon CAD Findings Summary sub-tree is empty. The Summary of Detections and Summary of Analyses sub-trees of the Document Root node contain detail about which (if any) algorithms succeeded or failed. If the code value indicates that there were no findings, then the code value can be used to determine whether colon CAD processing occurred successfully, without parsing the Summary of Detections and Summary of Analyses sub-trees.
