Figure A-8. Mammography CAD SR IOD Template Structure​

In Figure A-8, '···' indicates possible recursive application of subordinate Templates.​

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 ana-​ lysis of Mammographic evidence. This Template, together with its subordinate Templates, describes both the results for presentation​ toradiologistsandpartialproductresultsforconsumptionbymammographyCADdevicesinsubsequentmammographyCADreports.​

- Standard -​

DICOM PS3.16 2020a - Content Mapping Resource​

Page 293​

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,startingfromSingleImageFindings(seeTID4006“MammographyCADSingleImageFinding”),associatedasCompositeFeatures​ (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.​
