What is RadLex?
RadLex is a comprehensive lexicon for the indexing and retrieval of online radiology resources developed by the Radiological Society of North America (RSNA) and other radiology organizations, including the American College of Radiology (ACR). It has been designed to satisfy the needs of software developers, system vendors, and radiology users by adopting the best features of existing terminology systems, while producing new terms to fill critical gaps. RadLex also provides a comprehensive and technology-friendly replacement for the ACR Index for Radiological Diagnoses. Rather than “reinventing the wheel,” RadLex unifies and supplements other lexicons and standards, such as SNOMED-CT and DICOM.
