| Abstract | 「要旨」 近年, 骨粗鬆症をはじめ代謝性骨疾患の骨病態を把握するために, 種々の非侵襲的な骨塩定量法が開発され臨床に供されている. 各骨塩定量法は測定原理, 得られる指標, 測定部位, 測定精度, データ収集時間や被曝線量が異なるので, その特徴と問題点を熟知すべきである. これらの骨塩定量法のうち, 二重エネルギーX線吸収測定法 (DXA) は基本性能が優れており, 現在骨塩定量法の主流となっている. 本論文では, 骨塩定量の骨粗鬆症診断における役割, DXAによる測定の実際, 異なる測定部位間の骨密度値の相関, 経時的な測定の重要性や骨代謝マーカーとの関係を概説する. |

| Abstract | [Summary] To evaluate the skeletal state of bone pathophysiology in metabolic bone diseases including osteoporosis, various non-invasive bone mineral quantifying methods have been developed recently, and used clinically. As each bone quantifying method differs in its principle of measurement, the index obtained, the site of measurement, precision, data-acquisition time, and radiation dose, the characteristics of and problems with these methods should be kept in mind. Among these bone quantifying methods, the fundamental performance of dual-energy X-ray absorptiometry (DXA) is excellent, and it is the most popular bone quantifying method at present. In this paper, the role of bone quantifying methods in the diagnosis of osteoporosis, the actual procedure of measurement by DXA, the relation between bone mineral densities at different sites of measurement, the importance of longitudinal measurements, and the relation to bone metabolic parameters were reviewed. |
