【摘要】：目的：利用多层螺旋CT（MSCT）三维后处理技术测量儿童气管各径线，获得儿童气管影像解剖径线值，研究儿童气管各径线与年龄增长的变化趋势，比较MSCT测量值与尸体测量值的差异，为儿童气管解剖的研究积累资料，以期能为临床行气管插管、支气管镜检查等气道介入治疗时选择器械型号提供参考数据。同时对比X线平片测量结果，探讨利用MSCT研究儿童气管径线的应用价值。 材料与方法：回顾性分析从医学影像信息系统（PACS）上获得的2010年5月～2012年12月之间在我院就诊并拍摄胸部CT片的0～12岁长春地区儿童3124例。按年龄段分成0～3个月；4～6个月；7～9个月；10～12个月；1～3岁；4～6岁；7～9岁；10～12岁8个年龄组。检查仪器为德国Siemens16排螺旋CT。在PACS工作站上运用MSCT三维后处理技术获得重建图像，在多平面重组重建（MPR）图像上分别测量气管各径线值并进行详细记录，包括胸段气管长度、矢状径、横径和管壁厚度等。将新生儿气管横径和矢状径与国内新生儿尸体解剖数据进行对比。另外选取120例同时做胸部X线平片和CT检查的儿童，在两种检查方法所获得的图像上分别测量气管各径线值，并对两组结果进行对比。对所有数据进行统计学分析。 结果：在影像学解剖观察中，0～12岁各年龄组儿童胸段气管长度、横径、矢状径及气管管壁厚度的平均值如下：0~3个月分别为（28.9±4.9）mm、（5.9±0.5）mm、（5.2±0.7）mm、（1.5±0.2）mm；4~6个月分别为（29.7±4.9）mm（、6.5±0.6）mm（、5.6±0.7）mm（、1.6±0.2）mm；7~9个月分别为（30.6±4.8）mm、（6.7±0.6）mm、（6.0±0.8）mm、（1.7±0.2）mm；10~12个月分别为（31.0±4.9）mm、（7.0±0.7）mm、（6.2±0.9）mm、（1.8±0.2）mm；1~3岁分别为（32.5±5.1）mm、（8.1±0.9）mm、（7.3±1.0）mm、（2.0±0.2）mm；4~6岁分别为（36.6±6.8）mm、（9.1±0.9）mm、（8.5±1.3）mm、（2.0±0.2）mm；7~9岁分别为（43.1±8.9）mm、（10.5±1.0）mm、（10.3±1.4）mm、（2.1±0.2）mm；10~12岁分别为（51.2±10.4）mm、（11.8±1.2）mm、（12.3±1.8）mm、（2.4±0.3）mm。总体上，儿童气管各径线值均随着年龄段的增加而增大；气管横径大于矢状径，但个体差异较大。在两性儿童中，气管各径线值存在一定差异，男性儿童胸段气管长度大于女性儿童，但其横径和矢状径均小于女性儿童；两性儿童气管管壁厚度大致相等。MSCT测量新生儿气管横径和矢状径均略大于文献报道的尸体测量数据。X线片测量胸段气管长度值与MSCT重建图像测量值无明显差别；X线片测量气管横径值小于MSCT重建图像测量值。 结论：1.MSCT及其三维后处理技术对气管解剖结构显示清晰，直观易懂，测量方法简便无创，，适合进行大样本量的研究，是研究儿童气管解剖径线的有效途径。2.MSCT测量新生儿气管内径值略大于尸体测量数据，但更能反映儿童气管解剖径线的真实数值；3.运用MSCT研究各年龄段儿童气管解剖径线值有重要的临床意义。
[Abstract]:Objective: to measure the trachea diameter of children by using multilayer spiral CT (MSCT) 3D post-processing technique, to obtain the anatomic diameter of trachea image of children, to study the change trend of trachea diameter and age growth in children, and to compare the difference between MSCT measurement value and cadaveric measurement value. To accumulate data for the study of trachea anatomy in children, so as to provide reference data for the selection of instruments for clinical tracheal intubation, bronchoscopy and other airway interventional therapy. At the same time, the application value of MSCT in the study of tracheal diameters in children was discussed. Materials and methods: a retrospective analysis of 3124 children aged from 0 to 12 years old in Changchun who were admitted to our hospital from May 2010 to December 2012 to take chest CT films from the medical image information system (PACS) was analyzed. According to the age group, it was divided into 8 age groups: 0 ~ 3 months, 4 ~ 6 months, 7 ~ 9 months, 10 ~ 12 months, 1, 4, 6 years old, 7 ~ 9 years old, 10 ~ 9 years old, 12 years old, 8 age groups. German Siemens16 spiral CT. The reconstructed images were obtained by using MSCT 3D post-processing technique on PACS workstation. The trachea diameter, sagittal diameter, transverse diameter and wall thickness were measured and recorded in detail on the multiplanar reconstructed (MPR) images, including thoracic trachea length, sagittal diameter, transverse diameter and wall thickness. The trachea transverse diameter and sagittal diameter of neonates were compared with the autopsy data of domestic newborns. In addition, 120 children with chest X-ray and CT were selected to measure the trachea diameter values on the images obtained by the two methods, and the results of the two groups were compared. All the data were analyzed statistically. Results: the mean values of thoracic trachea length, transverse diameter, sagittal diameter and trachea wall thickness in children aged 12 years were (28.9 卤4.9) mm, (5.9 卤0.5) mm, (5.2 卤0.7) mm, (1.5 卤0.2) mm;4~ for 6 months, respectively (29.7 卤4.9) mm (6.5 卤0.6) mm (5.6 卤0.7) mm (1.6 卤0.2) mm;7~ for 9 months were (30.6 卤4.8) mm, (6.7 卤0.6) mm, (6.0 卤0.8) mm, (1.7 卤0.2) mm; for 9 months, respectively. 10~12涓湀鍒嗗埆涓
