The Dose Index Registry (DIR) Exam Name Mapping Tool allows you to map the study descriptions from your facility’s CT scanners to a standard terminology using the RadLex Playbook. This standardization categorizes exams consistently across facilities so that appropriate comparisons can be created in DIR feedback reports. Consequently, DIR feedback reports only include exams that you have mapped to a RadLex Playbook term.

A facility can supply the DIR with the RadLex Playbook ID (RPID) number, if available, for each exam in the structured report data sent via TRIADTM. If RPIDs are not available in your structured report data, you can use two other methods to map exam study description names to RPID values:

  • You can perform this task yourself using our on-line Exam Name Mapping Tool. You can use the tool to select RPIDs for each of your exams, or build your own custom RPID if you believe one is needed. You only need to map an exam to an RPID once.

  • You can contract with RadMapps, a certified vendor approved to perform the mappings on your behalf.

The Exam Name Mapping Process

If you decide to do your own mappings using the Exam Name Mapping Tool, start by mapping your high-volume exams and the exams that you are most interested in comparing to other facilities so that these data can be included in your next round of aggregate reports.


An exam will have one of the following statuses as it flows through the mapping process:

  • Not Tagged is for records that need tagging, and there are no suggestions available.

  • Tagging in Process indicates a new RPID tag has been created, via the Build Your Own Mapping function. After submitting the RPID from Build Your Own Mapping, the predicates and values you selected are sent to the Radiological Society of North America (RSNA) for review. The RSNA will either create a new RPID or suggest an existing, more applicable RPID, depending on the review’s findings.

Note: The review process can take up to three months and may not result in a new unique RPID.

  • Tagging Suggested indicates: either

    1. the mapping tool has identified an RPID that may be suitable based on similar exams mapped by other facilities, or

    2. the RSNA has completed its review of a requested mapping and has defined a new RPID or suggested an existing RPID be used.

  • Tagging Completed marks exams that you have mapped and verified.

Only exams with status Tagging Completed are included in aggregate reports.

  • Guidance marks an exam as a non-diagnostic study to be omitted from aggregate reports.

  • Unwanted is another option used to mark exams that should not be included in aggregate reports.


When you first begin submitting data to the DIR, all of your exams have a status of either Not Tagged or, if the software finds a potential match, Tagging Suggested. Regardless of which initial status they have, no exams will be included in aggregate reports until they are mapped to RPIDs and have a status of Tagging Completed. Therefore, it is essential that you review all exams with statuses of Not Tagged or Tagging Suggested and map them to an RPID. There are three methods available in the Exam Name Mapping Tool to do this:
