Accessing the Tool

To access the Exam Name Mapping Tool, start by logging in to NRDR, select DIR from Registry menu, and then select Exam Name Mapping from the DIR Registry menu. A prompt to select modality appears. Select the modality and then choose a facility from the list.

Note: Fluoroscopy is currently restricted to pilot participants only.

DIR ENMT CT Fluoro Prompt

Note: Exam Name Mappings created at the corporate account level override mappings created for individual facilities with the account - e.g. a mapping for study description CT Lung Screening at the corporate account level supersedes all mappings for that study description created by subordinate facilities.  Please coordinate with your Corporate Account Administrator, or contact the NRDR Help Desk if you have questions.

A list of all exam names that have been sent to the DIR from your facility appears. Buttons at the top of the screen allow you to change modality and facilities, if needed.DIR ENMT - Home Screen

The Search Function

There are several search functions available to help you sort through your facility’s exam records.

The Exam field allows you to select a subset of exam names. For example, if you type abdomen in the text box and then click the Search button, the search returns all exams with the term “abdomen” appearing anywhere in the description. The search is not case sensitive.DIR ENMT - Exam Search

Use the Clear button to reset the page to show all exams.

The Status field features a drop-down menu so you can select exams that are in various stages of “tagging” or mapping.DIR ENMT - Status Drop-Down

All exams for new facilities initially appear as either Not Tagged or Tagging Suggested.

The RPID field allows you to search by a specific RPID number for CT exams, or by ACR Common Procedure ID number for Fluoro exams.


Note: Unlike searching by Exam, searching by RPID or Common Procedure ID requires an exact match – e.g. the criterion RPID1 only returns CT study descriptions tagged with RPID1, and criterion 4011589 only returns Fluoro study descriptions tagged with 4011589.

You may also click on a letter of the alphabet to select all exam names beginning with that letter. For example, if you click on the letter H, the search returns all exams starting with that letter.DIR ENMT - Search by Letter

At a Glance Summary

The At a Glance line across the top of the page summarizes the number of exams for each Status. Clicking on the link next to each status executes a search for the specific Status selected – e.g. clicking on the 11 next to Tagging Completed retrieves all 11 exams with status Tagging Completed.DIR ENMT - At-a-Glance Shortcut

Mapping Exams

There are two ways to map exam study descriptions to RPID/Common Procedure values

  • Assign a mapping to a single study description by selecting it and clicking the Search RPID/Search Common Procedure button, found at the bottom of the mapping tool.

  • Upload multiple mappings by clicking the Export All to Excel button to create and download a file of all of your exams. You may then update the file and use the Upload button to apply the updates to your mappings.

Note: The Build your Own Mapping link is only available in the Fluoroscopy module.  It is now obsolete for CT exams. You may use the link or the Build Your Own Mapping Multiple button to manually assign predicate values for your own notation, but exams will not be used in aggregate comparison reports until they are manually mapped to an RPID or ACR Common Name.

Mark Exams as Tagging Completed

After you have reviewed the mappings for study descriptions with the status Tagging Suggested you may change the status to Tagging Completed. Select each study description by clicking the box to the left of the exam and then click the Mark Selection as Tagging Completed button in the lower right corner of the page.DIR ENMT - Mark as Tagging Completed

If you wish to mark all exams with status Tagging Suggested at the same time, you may do so by selecting Tagging Suggested under the drop-down menu by the Status button and then clicking on Mark all Tagging Suggested as Tagging Completed.

Please do not click this button unless you have reviewed all the suggested tags.

Change the Mapping for Tagging Completed Exams

If you assigned a mapping to a study description and later decide that you want to change it, select the study description and then clicking the Mark as Not Tagged button. This changes the status to Not Tagged and you may create a different mapping.DIR ENMT - Mark as Not Tagged
