摘要
目的：ＣＴ测量国人肺动脉直径。材料和方法：对１００例成人胸部行双螺旋ＣＴ扫描，在六个位置测量肺动脉直径。结果：主肺动脉直径，男２５．２±２．５ｍｍ，女２３．９±２．４ｍｍ；右肺动脉近端直径，男２０．９±２．５ｍｍ，女１９．５±２．１ｍｍ；右肺动脉远端直径，男１６．５±２．２ｍｍ，女１５．５±２．４ｍｍ；左肺动脉直径，男１９．１±２．９ｍｍ，女１８．０±２．５ｍｍ；右下肺动脉直径，男１１．２±１．７ｍｍ，女１１．１±１．５ｍｍ；左下肺动脉直径，男女均为１０．７±１．３ｍｍ。结论：ＣＴ可以测量肺动脉直径，中心肺动脉直径男女有显著差异（Ｐ＜０．０５），双下肺动脉直径男女无显著差异（Ｐ＞０．０５）。
Purpose:To measure the normal pulmonary artery size.Materials and Methods:100 normal adults were scanned with double helical CT and the pulmonary artery size were measured in six pionts.Results:the main pulmonary artery is 252±25mm for male and 23.9±2.4mm for female,the proximal right is 20.9±2.5mm for male and 19.5±2.1mm for female,the distal right is 16.5±2.2mm for male and 15.5±2.4mm for female,the left is 19.1±2.9mm for male and 18.0±2.5mm for female,the interlobar is 11.2±1.7mm for male and 11.0±1.2mm for female,the left descending is 10.7±13mm for male and female.Conclusion:CT can measure the pulmonary artery size,there was significant difference at central pulmonary artery and no significant difference at distal pulmonary artery between male and female.
