1健康老年妇女近段股骨骨密度和结构的定量CT研究显示文摘目的采用定量CT(QCT)和双能X线吸收测量(DXA)仪对健康老年妇女近段股骨骨密度(BMD)和骨结构进行研究,并对2种测量方法的结果进行比较。方法对66名65岁以上健康妇女左侧髋关节进行DXA测量,计算出股骨颈和粗隆区BMD;对其双侧近段股骨进行QCT测量,计算出股骨颈、粗隆区和整体股骨ROI的皮质骨、松质骨和总体骨的BMD和体积;并将QCT三维图像模拟DXA的平面投影计算出模拟DXA股骨颈BMD和模拟DXA股骨粗隆区BMD。对所获数据进行配对t检验或非参数秩和检验,并用Pearson法分析DXA和QCT相对应ROI的相关性。结果用QCT可以对股骨近段不同ROI(股骨颈、粗隆区和整体股骨区)及不同骨成分(皮质骨、松质骨和总体骨)的BMD及体积等参数进行精确的定量分析。除右侧股骨颈皮质骨BMD[(0.52±0.04)g/cm^3]、股骨粗隆区皮质骨BMD[(0.49±0.03)g/cm^3]、股骨粗隆区综合骨BMD[(0.22±0.04)g/cm^3]大于左侧相应参数[分别为[(0.51±0.04)、(0.48±0.03)、(0.21±0.04)g/cm^3],差异均有统计学意义(P值均〈0.05),但差别均〈3.3%;而模拟DXA股骨颈BMD、模拟DXA股骨粗隆区BMD、股骨颈皮质骨体积、股骨颈松质骨BMD、股骨颈松质骨体积、股骨颈综合骨BMD、股骨颈综合骨体积、股骨粗隆区皮质骨体积、股骨粗隆区松质骨BMD、股骨粗隆区松质骨体积、股骨粗隆区综合骨体积左侧参数分别为(0.52±0.10)g/cm^2、(0.78±0.13)g/cm^2、5.80cm^3、(0.06±0.03)g/cm^3、(5.19±1.40)cm^3、(0.25±0.04)g/cm^3、15.66cm^3、(21.74±3.43)cm^3、(0.08±0.03)g/cm^3、(34.27±6.09)cm^3、(76.12±11.11)cm^3,右侧分别为(0.52±0.10)g/cm^2、(0.78±0.13)g/cm^2、6.01cm^3、(0.06±0.02)g/cm^3、(5.17±1.27)cm^3、(0.25±0.04)g/cm^3、15.62cm^3、(22.12±3.60)cm^3、(0.09±0.03)g/cm^3、(34.17±5.94)cm^3、(76.53±10.71)cm^3,差异均无统计学意义(P值均〉0.05)。左右两侧近段股骨QcT各相对应参数之间的r值范围在0.656~0.955,均具有相关性(P〈0.05)。QcT模拟DXA股骨颈和粗隆区BMD与真正DXA测量的相应值之间r值分别为0.685和0.855,具有相关性(P〈0.05)。结论利用QCT技术可以对老年妇女近段股骨不同区域和不同成分的BMD和结构进行精确定量分析,QCT是骨质疏松研究中非常有用的测量技术。程晓光 Li Jing 刘霞 王予生 李谨 屈辉 H Genant T Lang 2009中华放射学杂志2009,43,2:8
