The Radiological Society of North America (RSNA) lexicon RadLex is now available in German online. This standardized terminology supports structured radiology reporting and case indexing, enhancing data comparison and interoperability.
Area of Science:
- Radiology
- Medical Informatics
- Linguistics
Background:
- The Radiological Society of North America (RSNA) developed RadLex, a standardized lexicon for radiological terms, starting in 2003.
- RadLex aims to facilitate structured reporting of imaging findings and indexing of teaching cases.
Purpose of the Study:
- To translate the first version of RadLex (1-2007) into German.
- To implement a language-independent online term browser for RadLex.
Main Methods:
- Independent translation of 6303 RadLex terms by two radiologists using medical dictionaries.
- Consensus-based revision of terms with differing translations.
- Development of an online term browser using morphosemantic indexing for language-independent search.
Main Results:
- 99% (6240/6303) of RadLex terms were translated into German.
- The online browser supports language-independent searches in RadLex (German/English) and other medical terminologies (e.g., ICD 10).
- The browser displays term hierarchies and translations, with adaptable result list complexity.
Conclusions:
- The German version of RadLex (1-2007) is accessible online via an efficient search browser.
- This resource is crucial for comparing national and international radiological examination results.
- It promotes interoperability between digital teaching resources in radiology.

Radiological Investigation I: X-ray and CT
Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
