The RadLex Playbook is a radiology procedure naming system created by the Radiological Society of North America (RSNA). Each Playbook procedure has a unique code, the RadLex Playbook identifier (RPID). A RPID is defined by a set of attribute values that each describes one part of the exam,such as modality (e.g., CT, XR, US), modality modifier (such as angiography for CT), use of pharmaceuticals (e.g., biliary contrast) and body part (such a s Carotid Artery Bilateral). Each distinct attribute value is assigned a RadLEx identifier (RID).
Here’s an example:
RPID2492 XR ABDOMEN AP
RID10345 PROJECTION RADIOGRAPHY
Keep in mind the following tips to help you map your radiological exams to RadLex Playbook:
- We found it is easier for mapping to download the csv file of the playbook, rather than using the online browser. You can filter the various columns to narrow down your search by opening the csv file as a spreadsheet.
- Due to procedure naming convention and lack of ordering by a particular field, browsing the entire file can be a challenge. Instead, first filter by modality, then by modality modifier if applicable. This reduces the number of rows you need to review to find a match.
- The Playbook has some terms that are duplicated in every way except for the RPID and the description of the term use – one is an orderable whereas the other is a protocol, e.g.:
RPID188 CT ABD- A computed tomography RADIOLOGY ORDERABLE imaging procedure
focused on the abdomen.
RPID839 CT ABD- A computed tomography IMAGING PROTOCOL imaging procedure focused
on the abdomen.
Select the orderable if you’re mapping a radiological exam.
- Be aware of the status of the RPID – active, deprecated, discouraged or trial. You may want to consider RPIDs with trial status in addition to active ones.
- RadLex Playbook is not yet complete; attribute sets are not necessarily consistent, as seen in the following examples (as of the current RadLex version 2.1 at this writing):
|RadLex Playbook||Not in RadLex Playbook|
|RPID2547 XR LOWER EXTREMITY 3 VIEWS KNEE||XR LOWER EXTREMITY 3 VIEWS KNEE LEFT|
|RPID2653 XR LOWER EXTREMITY 3 VIEWS KNEE BILATERAL|
|RPID4755 XR LOWER EXTREMITY 3 VIEWS KNEE RIGHT|
|RPID4730 XR UPPER EXTREMITY 3 VIEWS HAND LEFT||XR UPPER EXTREMITY 3 VIEWS HAND BILATERAL|
|RPID4725 XR UPPER EXTREMITY 3 VIEWS HAND RIGHT|
|RPID2542 XR UPPER EXTREMITY 2 VIEWS HAND||XR UPPER EXTREMITY 2 VIEWS HAND LEFT|
|RPID2543 XR UPPER EXTREMITY 2 VIEWS HAND BILATERAL|
|RPID4736 XR UPPER EXTREMITY 2 VIEWS HAND RIGHT|
Future releases of RadLex Playbook may add the missing terms.
