【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(P0.05),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(P0.05)。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。
[Abstract]:Objective: to measure the condylar volume, surface area and MI value of normal population by Mimics software, and to study the condylar morphological characteristics of different position, sex and age. Methods: three hundred patients from radiology department of 6th people's Hospital affiliated to Shanghai Jiaotong University were selected from the reference value of condyle volume and surface area in order to establish the reference value of condyle volume and surface area of normal population. They were divided into three groups according to their age: group 1: group 1: 18 ~ 24 years old, group 2: 25 ~ 34 years old, group 3: 35 ~ 44 years old, each group 100 cases, male and female 50 cases. Then multislice spiral CT was performed, and 3D reconstruction of bilateral condylar process was performed with Mimics17.0 software, and condylar volume was calculated. Results: there was no significant difference in the volume, surface area and MI value of the left and right condyle. The surface area of the condyle was larger than that of the female (P 0.05), but there was no significant difference in the MI value of condyle between male and female. There was no significant difference in the volume and surface area of condyle between different age groups. The MI value of 35 ~ 44 year old individuals was higher than that of 1824 year old individuals (P 0.05). Conclusion the volume and surface area of condyle can be measured effectively by using the software of: mimics, and the reference value of condyle volume and surface area can be established in normal population.
