The Dose Index Registry (DIR) Exam Name Mapping Tool allows you to map or "tag" the study descriptions from your facility’s exams using a standard terminology. This standardization categorizes exams consistently across facilities so that appropriate comparisons can be provided in feedback reports. Consequently, DIR aggregated feedback reports, such as the DIR Executive Summary and QCDR Preview report, only include exams that you have tagged using the Exam Name Mapping tool.

As of February 2019, the Exam Name Mappings tool supports both DIR CT and DIR Fluoro and DR exams. DIR CT exams are tagged using RadLex Playbook IDs (RPIDs), and DIR Fluoro and DR exams are tagged using ACR CommonTM Procedure names.

For CT exams, a facility can supply the RadLex Playbook ID (RPID) number, if available, for each exam in the structured report data sent to the DIR 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. 

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

DIR Fluoro and DIR DR participants must use the Exam Name mapping tool to map each study description to an ACR Common Procedure.

Corporate Account and Facility Account Mappings

Exam Name Mappings may be defined at either the corporate account level or facility level. Corporate Account Administrators (CAAs) and Service Users may define mappings for any facility within their corporate account. CAAs may also define mappings for the corporate account ID, e.g. by selecting facility 200007 - (Master) from the list below, the CAA can define mappings at the corporate level that will be applied to all facilities within that account.DIR Exam Name Mapping Facilities List - CAA

All other users may define mappings for the individual facilities to which they have access.

Note: A user can manage mappings for all facilities within the Corporate Account by having the CAA add a Service User profile to their user account.

Note: Facility Administrators, Registry Administrators, and Facility Users should coordinate with their Corporate Account Administrator before defining their mappings to make sure they do not create a duplicate mapping for the same study description. Mappings defined at the corporate account level will override mappings at the facility account level. Please contact the NRDR Help Desk if you have any issues or questions.

Exam Name Mapping Settings

In order to view or update current mapping settings for your facility or corporate account use Exam Name Mapping Settings page located on the DIR left menu. Users can use the page to set up name mapping rules for CT exams or Projection X-ray procedures, e.g., fluoroscopy and digital radiography, by selecting one of the following options:

  1. Corporate Level Name Mapping Option: Select this option for mapped CT exams or Projection X-ray procedures to automatically apply to ALL facilities within the corporate account. 

  2. Facility Level Name Mapping Option: Select this option for mapped exams or procedures to apply ONLY to the selected facility and not to any other facility within the corporate account.

The Exam Name Mapping Process

If you decide to tag your study descriptions 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.

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 for CT exams, Tagging Suggested. If marked as Not Tagged, you must manually standardize the exam name by mapping it to an RPID (CT exams) or ACR Common Procedure Name (Fluoro and DR exams). If a mapping is marked as Tagging Suggested, you should review the tagging and either confirm it or choose a different mapping.

Note: Exams are included in quarterly aggregate reports if they having a mapping status of either Tagging Suggested or Tagging Completed. All other exams are excluded from aggregate reports.

There are two ways to map a study description to a standardized term:

Note: The Build your Own Mapping link is only available in the Fluoroscopy module.  It is now obsolete for CT exams. You may still use the link to manually assign predicate values for your own notation; however, doing so changes the tagging status to Tagging in Process and affected exams will not be used in aggregate comparison reports until they are manually mapped to an ACR Common Procedure.

The exam name mapping workflow is summarized in the flowchart, below.

The table, below, summarizes the  statuses and corresponding actions of the standardization/mapping process.


Action Needed

Exam Used in Comparison Reports?

Not Tagged

Manually map the study description, using the Search RPID or Search by Common Procedure button to find the best mapping.


Tagging Suggested

Review the suggested mapping and either confirm it or manually map it yourself

Note: Applies to CT exams only


Tagging in Process

Create a mapping manually

Note: This status applies for only Fluoro and DR mappings started via the Build Your Own Mapping function. Exams will not be used until you manually map the study description.


Common ID Requested

Request a new ACR Common ID

Note: This status applied for only Fluoro and DR mappings started via the Mark selection as Common ID Requested function.  Exams will not be used until you manually map the study description.


Tagging Completed

No action necessary


Guidance or Unwanted

No action necessary; indicates exams should not be used in comparison reports

Note: Applies to CT exams only
