Research Abstract

当初研究計画及び研究成果等
① 続発性骨粗鬆症と対照例の骨梁パラメータの差の統計解析:多発性骨髄腫と対照間で骨梁幅、骨異方性度、フラクタル次元に有意差を検出した。胃切除後症例と対照間、および肝動脈塞栓療法除後症例と対照間で続発性骨粗鬆症有病率、骨梁パラメータおよび有限要素解析による破壊荷重、スティフネスに有意差を検出した。
② 脊椎骨折を生じる骨梁パラメータの閾値の決定:骨折症例の蓄積中である。横断的検討では多発性骨髄腫骨折群と非骨折群間で、骨梁パラメータおよび機械特性に有意差を検出した。
③ DXA骨密度と骨梁パラメータの脊椎骨折予測能を比較:DXAによる面積骨密度に対してCTによる体積骨密度の優位性を示すエビデンスが蓄積されており、申請者らは平成23年度よりcalibration phantomを用い、CTによる体積骨密度および組織骨密度で評価している。上述の各検討において組織骨密度に有意差を検出している。②同様、骨折症例の蓄積中である。
