Clin Oral Invest:使用MSCT评估髁突形态和位置

2018-08-25 MedSci MedSci原创

本研究的目的是应用Mimics 17.0软件研究正常人群中髁突的体积,表面,形态指数(MI)和位置。然后,探讨左右两侧,性别和年龄的差异,建立正常人髁突形态和位置的参考值,有助于研究异常个体的髁突形态和位置特征。

本研究的目的是应用Mimics 17.0软件研究正常人群中髁突的体积,表面,形态指数(MI)和位置。然后,探讨左右两侧,性别和年龄的差异,建立正常人髁突形态和位置的参考值,有助于研究异常个体的髁突形态和位置特征。

研究纳入了来自上海交通大学附属第六人民医院放射科的300名受试者。根据年龄将他们分为三组:第1组(18-24岁),第2组(25-34岁)和第3组(35-44岁)。每组包括100名受试者(50名男性和50名女性)。之后使用多层螺旋计算机断层扫描(MSCT)进行检查。所有髁突图像均由Mimics 17.0软件重建,以测量髁突的体积,表面和MI,并通过关节间隙分析髁突在关节窝中的位置。

结果:左右两侧髁突体积,表面和MI的差异不明显(P> 0.05)。男性的髁突体积和表面大于女性(P <0.05),而髁突MI无差异(P> 0.05)。三个年龄组的体积和表面没有统计学差异。然而,第1组的MI在统计学上低于第3组(P <0.05)。左右髁突的位置无显着差异(P> 0.05)。然而,髁突位置在性别和年龄方面存在显着差异(P <0.05)。

本研究显示左右两侧髁突形态和位置无显着差异,但性别和年龄因素对髁突形态和位置有一定影响。该研究结果可用于建立正常亚洲人群中髁突形态和位置的临床诊断标准。

多排CT(multidetector CT, MDCT)和多层CT(multi-slice CT, MSCT)的区别

多排CT(multidetector CT, MDCT)和多层CT(multi-slice CT, MSCT)的区别 “排”是指CT扫描机探测器的阵列数,一般排数越多,探测器宽度越宽,一次扫描完成的宽度越大。有人将多“排”CT称为多 “层”CT(multislice CT,MSCT),在一般情况下两者的含义相同,即有多少“排”探测器,一次扫描即可完成多少“层”图像的采集。但是,如果每排探测器一
