摘　　要：目的利用多层螺旋CT（MSCT）测量兰州地区健康成人心肺血管管径及面积，制定本地区成人心肺大血管管径及面积的正常标准，并与既往文献报道的其他地区健康人的所测数据进行对比。方法选择常住于兰州，没有心肺疾患的健康体检者。按年龄分为：18～39岁（A组），40～60岁（B组），61—80岁（C组）。各组均包括男50例，女50例，共300例。采用平静呼吸状态下深吸气末时扫描，所得图像经工作站行3D重组后进行测量，所得结果行统计学分析。结果不同年龄组间，主肺动脉、右肺动脉、左肺动脉、升主动脉及降主动脉的管径及面积差异有统计学意义（P〈0．05）。B组与C组中，主肺动脉、右肺动脉、左肺动脉的管径及面积具有明显的性别差异（P〈0．05）。结论本实验为兰州地区成年人心肺动脉相关疾病的早期诊断提供了较好的影像学标准。与以往文献比较，兰州地区健康成人所测结果异于其他地区成人，推测与本地地理环境及空气质量有关。Objective To constitute a normal standard of cardiopulmonary vascular diameter and size of normal aduh in Lanzhou, and to compared with the other＇s data reported in the previous bibliography by measuring diameter and area of cardiopulmonary artery lumen of the healthy adults in Lanzhou with multislice spiral CT （MSCT）. Methods Three hundred Lanzhou adults with no eardiopulmonary disease were equally assigned to 3 groups according to their age （A group： 18-39 years, B group： 40-60 years, C group： 61-80 years; 50 females and 50 males in each group）. CT data were acquired at the end of deep inspiration phase and measurements were done on 3D reconstruction image with precise landmarks. All the results were statistically analyzed. Results The diameters and areas of the main pulmonary artery, left pulmonary artery, fight pulmonary artery, ascending aorta and descending aorta differed significantly among the 3 groups （P〈0.05）. In groups B and C, there were significant differences in diameters and areas of pulmonary artery, left pulmonary artery, and right pulmonary between different genders （P〈O.05）. Conclusion Imaging standard is provided for Lanzhou adult in early diagnosis of cardiopulmonary disease. The diameters and areas of main pulmonary artery, left pulmonary artery, and right pulmonary artery of Lanzhou healthy adults are different from that of other regions. It may be related to the geographical environment and the state of air pollution in Lanzhou.
