Outline of Annual Research Achievements

① CT-based FEMにより、ダイナミックCT検査による放射線被曝が骨質の低下と腰椎の骨強度を減少させることを示した(PLoS One. 2014 Oct 16;9(10): e110106、RSNA The 101th Annual Meeting December. 2015, Chicago, USA)。自家末梢血幹細胞移植が腰椎骨密度と骨強度に及ぼす影響をCT-based FEMを用いて検討した(RSNA The 102th Scientific Assembly and Annual Meeting December. 2016, USA)。
② 多発性骨髄腫の骨折予測に骨梁微細構造解析とCT-based FEMによる骨強度解析が有用であることを示した(J Musculoskelet Disord Treat 2016 2(4): 2:019、RSNA Annual Meeting (December. 2014, USA)。多発性骨髄腫患者の腰椎骨微細構造と骨強度に及ぼすbortezomibとlenalidomideの影響をCT-FEMを用いて縦断的に検討した (Clin Lymphoma Myeloma Leuk. 2014 Dec;14(6): 485-92)
③ 腰椎摘出標本を用いて3T-MRI-, 64列CT-, Micro-CT間の骨梁微細構造パラメータの比較と正確性を検討した(ISMRM 22th Scientific Meeting And Exhibition (May. 2014, Milan, Italy)。骨梁構造と骨強度計測に与える逐次近似法の影響を腰椎摘出標本とMicro-CTを用いて検討した(RSNA The 101thAnnual Meeting December. 2015, USA)。
