Mimics软件在髁突体积和表面积测量中的应用
|
Abstract:
摘要 目的:运用Mimics软件测量正常人群髁突体积、表面积和MI值,探讨不同位置、性别、年龄的髁突形态特点,为确立正常人群髁突体积和表面积参考值提供参考。方法:从上海交通大学附属第六人民医院放射科就诊患者中选取符合纳入标准的研究对象300例,根据年龄分为3组:组1(18~24岁),组2(25~34岁),组3(35~44岁)。每组100例,其中男女各50例。然后进行多层螺旋CT检查,并运用Mimics17.0软件对双侧髁突进行三维重建,计算髁突体积、表面积和MI值。结果:左右侧髁突体积、表面积和MI值均无明显差别,男性髁突体积、表面积都要大于女性(P<0.05),但男女之间髁突MI值无显著性差异。不同年龄个体之间髁突的体积和表面积未见明显差别,而35~44岁个体的MI值要大于18~24岁个体(P<0.05)。结论:Mimics软件可以有效地测量髁突的体积和表面积,并为确立正常人群髁突体积和表面积参考值提供参考
