Quantitative parameters of bone microarchitecture were assessed by μCT in the T5 facet of an NF1 patient with dystrophic scoliosis versus the T7 facet of a control patient with idiopathic scoliosis but without NF1.

Bone volume fraction (BV/TV), connectivity density (Conn.D., mm−3), trabecular number (Tb.N, mm−1), trabecular thickness (Tb.Th mm), trabecular separation (Tb.Sp, mm), bone surface/bone volume ratio (BS/BV, mm−1), and density anisotropy (DA) were quantified as shown. Abbreviations: Bone volume fraction (BV/TV), connectivity density (Conn.D.), trabecular number (Tb.N), trabecular thickness (Tb.Th), trabecular spacing (Tb.Sp), bone surface/bone volume (BS/BV), density anisotropy (DA).Quantitative parameters of bone microarchitecture were assessed by μCT in the T5 facet of an NF1 patient with dystrophic scoliosis versus the T7 facet of a control patient with idiopathic scoliosis but without NF1.

如文中所述，对骨体积分数（Bone volume fraction, BV/TV）、连通密度（connectivity density, Conn.D., mm⁻³）、骨小梁数量（trabecular number, Tb.N, mm⁻¹）、骨小梁厚度（trabecular thickness, Tb.Th, mm）、骨小梁分离度（trabecular separation, Tb.Sp, mm）、骨表面积/骨体积比（bone surface/bone volume ratio, BS/BV, mm⁻¹）及密度各向异性（density anisotropy, DA）进行了定量表征。
缩写说明如下：骨体积分数（BV/TV）、连通密度（Conn.D.）、骨小梁数量（Tb.N）、骨小梁厚度（Tb.Th）、骨小梁间距（trabecular spacing, Tb.Sp）、骨表面积/骨体积（BS/BV）及密度各向异性（DA）。
本研究通过显微CT（μCT），对1例伴营养不良性脊柱侧凸的神经纤维瘤病1型（NF1）患者的胸椎5节段关节突，与1例特发性脊柱侧凸但无NF1的对照患者的胸椎7节段关节突的骨微结构定量参数进行了对比评估。
