RadLex radiology lexicon
We recognize the benefits that come from radiologists using common language to communicate diagnostic results. For this reason, RSNA produced RadLex®, a comprehensive set of radiology terms for use in radiology reporting, decision support, data mining, data registries, education and research.
RadLex provides the foundation for vital data resources used in radiology:
- The LOINC/RSNA Radiology Playbook
- RadElement Common Data Elements
- RadReport Radiology Reporting Templates
The development of RadLex has been supported by the National Institute of Biomedical Imaging and Bioengineering (NIBIB) and the cancer Biomedical Informatics Grid (caBIG) project.
RadLex is licensed freely for commercial and non-commercial users. Review and download the license.

LOINC/RSNA Radiology Playbook
The wide variation in the way radiology procedures are named in radiology departments makes ordering and protocoling less efficient and radiology records difficult to aggregate or compare across sites. The LOINC/RSNA Radiology Playbook was created to address this critical problem. Building on RadLex, RSNA developed names for nearly 1,000 commonly performed radiology procedures. Playbook provides a standard system for naming radiology procedures, based on the elements that define an imaging exam such as modality and body part. By providing standard names and codes for radiologic studies, Playbook supports operational and quality improvement efforts, including workflow optimization, chargemaster management, radiation dose tracking, enterprise integration and image exchange.
Today radiology facilities generally make up their own codes and names for radiology exams. The RadLex Playbook offers an agreed set of names for radiology procedures to enhance information sharing and data analysis.
Features and benefits
Each Playbook exam name includes a unique numerical code (Radlex Playbook Identifier, or RPID) and a set of procedure names of varying length and readability for use in different applications. The Playbook can support your practice by:
- Promoting interoperability of imaging exams
- Facilitating quality improvement, outcomes research and data analysis
- Enabling integration of radiology with enterprise systems
- Simplifying participation in data registries
- Offering optimization to workflow, billing management and radiation dose tracking
