Sign InRadLex — Standardized Radiology Lexicon
What Is RadLex?
RadLex is a comprehensive, controlled terminology for radiology developed and maintained by the RSNA (Radiological Society of North America). With over 68,000 terms covering anatomy, pathology, imaging techniques, and devices, RadLex provides a unified vocabulary for radiological communication.
The terminology is designed to support structured reporting, data mining, and artificial intelligence model training in radiology. It includes the RadLex Playbook, a standardized nomenclature system for radiological procedure names that facilitates study comparison across institutions.
RadLex complements other standards such as DICOM and SNOMED CT. While DICOM standardizes imaging and its transmission, and SNOMED CT covers general clinical terminology, RadLex specializes in radiology-specific vocabulary, providing the granularity needed for precise reporting and data analysis.
Why It Matters in Healthcare
- Structured reporting: provides standard terminology for creating consistent and comparable radiology reports across institutions.
- Data mining: facilitates searching and analyzing radiology findings across large clinical databases.
- Artificial intelligence: RadLex terms serve as the foundation for data labeling in AI projects applied to radiology.
- Procedure standardization: the RadLex Playbook unifies radiological procedure names for comparison and analysis.
- DICOM complement: enriches DICOM data with radiology-specific clinical terminology.
- Clinical research: enables aggregation of radiology data for multicenter studies.
