title: [What is it called? A formulation and glossary for the finding and understanding of results in HRCT of the lung].
abstract: In HRCT reports multiple different, often synonymous, German and English terms are used. The variety of terms impede understanding and acceptance of HRCT. Purpose of this paper is to present a scheme, which is based on the anatomic landmarks (secondary lobule), and the density of pathologic changes, as well as a glossary from the German HRCT-literature, including suitable terms, definitions, synonyms and English terms. Low attenuation changes include emphysemas, air-filled cavities (bullae, cysts, cavitations, honeycombing) and bronchial dilatation, changes with increased density consist of diffuse (ground glass opacity, consolidation) and focal processes (reticular and nodular densities). Reticular densities are categorised in thickened interlobular septae and translobular lines with differentiation of a reticular pattern and curvilinear lines. Nodular processes are categorised according to size, density, morphology, localisation and distribution. Parenchymal distortion and destruction indicate the severity of these processes. Certain patterns are indicative for possible differential diagnoses, and a recommendation for further procedures is given.
