TID 4000 Mammography CAD Document Root

This template forms the top of a content tree that allows a mammography CAD device to describe the results of detection and analysis of Mammographic evidence. This template, together with its subordinate templates, describes both the results for presentation to radiologists and partial product results for consumption by mammography CAD devices in subsequent mammography CAD reports.

This template defines a Container that contains an Image Library, the mammography CAD results, and summaries of the detection and analysis algorithms performed. The Image Library contains the Image SOP Class and Instance UIDs, and selected attributes for each image referenced in either the algorithm summaries or mammography CAD results.

The Summary of Detections and Summary of Analyses sub-trees gather lists of algorithms attempted, grouped by success/failure status. Algorithms not attempted are not mentioned in these sub-trees. This information forms the basis for understanding why a mammography CAD report may produce no (or fewer than anticipated) results. Mammography CAD results are constructed bottom-up, starting from Single Image Findings (see TID 4006 “Mammography CAD Single Image Finding”), associated as Composite Features (see TID 4004 “Mammography CAD Composite Feature”), and from which Individual and Overall Impressions are formed.

See Figure E.1-1 “Top Levels of Mammography CAD SR Content Tree” in PS3.17 .

Image Library	The "Image Library" section of the Content Tree (TID 4000 “Mammography CAD Document Root”, row 3) shall include all Image SOP Instances from the Current Requested Procedure Evidence Sequence (0040,A375) attribute of the SR Document General module. If a portion of another instance of a Mammography CAD SR IOD is duplicated in the "Overall Impression/ Recommendation" section of the Content Tree, the "Image Library" shall also include all Image Library Entries referenced from the duplicated portions of the Mammography CAD SR.

TID 4001 Mammography CAD Overall Impression/Recommendation

This template forms the top of the mammography CAD results sub-tree. The contents of this template describe the overall impression the mammography CAD device had for the mammographic evidence presented and any recommendations that the mammography CAD device made. The details of the overall impression and recommendation are expressed in this instance of the Mammography CAD Impression/Recommendation Body (see TID 4002 “Mammography CAD Impression/Recommendation Body”). The data from which the details are inferred, are expressed in the Mammography CAD Individual Impression/Recommendations (see TID 4003 “Mammography CAD Individual Impression/Recommendation”), of which there may be several.

CAD Processing and Findings Summary

This code value is used to express if and why the Overall Impression/Recommendation 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 mammography CAD processing occurred successfully, without parsing the Summary of Detections and Summary of Analyses sub-trees.

There are no constraints regarding the 1-n multiplicity of the inclusion of TID 4003 “Mammography CAD Individual Impression/Recommendation” or its underlying structure, other than the TID 4001 “Mammography CAD Overall Impression/Recommendation” and TID 4003 “Mammography CAD Individual Impression/Recommendation” requirements. Individual Impression/Recommendation containers may be organized, for example per image, per finding or composite feature, or some combination thereof.

TID 4002 Mammography CAD Impression/Recommendation Body

The details of an impression and recommendation are expressed in this template. It is applied to both Mammography CAD Overall Impression/Recommendation (TID 4001 “Mammography CAD Overall Impression/Recommendation”) and Mammography CAD Individual Impression/Recommendation (TID 4003 “Mammography CAD Individual Impression/Recommendation”).

Content Item Descriptions

Maximum CAD Operating Point	The maximum possible value of CAD Operating Point for this type of Detection Performed. No CAD Operating Point value recorded in the CAD Processing and Findings Summary sub-tree of the report for this type of Detection Performed shall exceed this value. The report may or may not contain Rendering Intent = "Presentation Optional" detections that are assigned the maximum value.
Recommended CAD Operating Point	A number indicating which of the CAD operating points is recommended by the creator of a CAD SR instance as the first operating point to be used when rendering the CAD SR instance contents. Subsequent changes to the displayed operating point are implementation dependent.
