128层螺旋 CT 在Ⅰ型骨质疏松症诊断中的临床应用

Clinical application of the 128 layer multi-spiral CT in the diagnosis of typeⅠosteoporosis

目的：探讨128层螺旋 CT 多项技术在Ⅰ型骨质疏松症诊断中的临床应用价值。方法收集100例Ⅰ型骨质疏松症患者的128排螺旋 CT 腰椎薄层高分辨扫描、多平面重建图像观察结果，并与双能 X 线吸收测定（DEXA）检查结果对照。结果100例Ⅰ型骨质疏松症患者128层螺旋 CT 在诊断骨小梁等细微结构、形态学观察、稳定性及是否合并骨折与 DEXA 骨密度（BMD）检测骨质疏松有较强互补性，椎体骨松质 CT 值测量与 DEXA 骨密度 T 值间有高度相关性。结论128层螺旋 CT 对Ⅰ型骨质疏松症诊断有较高临床应用价值，是 DEXA 骨密度检测必要的补充检查。

Objective To investigate the clinical application value of the 128 layer multi-spiral CT（ MSCT）multi-technologies on the diagnosis of type Ⅰosteoporosis. Methods The 128 MSCT lumbar scanning results and multi-planar reconstruction images of 100 patients with typeⅠosteoporosis were collected,and the results were compared with the dual-energy X-ray absorptiom-etry（DEXA）inspection. Results The 128 layer MSCT of 100 patients with typeⅠosteoporosis had complementarity with DEXA bone mineral density（BMD）to detect osteoporosis in the diagnosis of bone trabecula structure,vertebral morphological observation,stability and whether combined with fracture. Vertebral cancellous bone CT value measurement was highly correlated with DEXA bone mineral density T value. Conclusions The 128 layer MSCT has high clinical application value on the diagnosis of typeⅠosteoporosis,and it is one necessary supplement examination of DEXA bone mineral density detection.
