title: Peripheral quantitative computed tomography of the proximal radius in young subjects--new reference data and interpretation of results.
abstract: The aim of this contribution is to provide reference data for peripheral quantitative computed tomography (Stratec XCT2000) performed at the proximal radius (the so-called '65% site') of young subjects and to discuss the interpretation of such analyses. Data from a previous reference data study on 469 subjects between 6 and 40 years were re-analyzed and smooth curves were fitted. The corresponding equations allow for calculation of age-, height- and sex-specific z-scores of total cross-sectional area, cortical cross-sectional area, bone mineral content, cortical bone mineral density, total bone mineral density, Strength-Strain Index, muscle cross-sectional area and the ratio between bone mineral content and muscle cross-sectional area. These data should facilitate the clinical use of peripheral quantitative computed tomography in young subjects.
