摘　　要：目的利用多层螺旋CT对人肺动脉干、右肺动脉和左肺动脉成像,测量评价肺动脉干、右肺动脉和左肺动脉。方法选取正常人340例,胸部多层螺旋CT增强扫描,将图像传至工作站进行三维重建,观察测量肺动脉干、右肺动脉和左肺动脉,然后对肺动脉干、右肺动脉和左肺动脉进行比较分析。结果①螺旋CT扫描成像测量的肺动脉的管径明显小于X线测量的肺动脉的管径,有统计学意义(P<0.05);②男、女性别之间的肺动脉管径也有显著差异(P<0.05);③不同年龄组别之间的肺动脉也有差异(P<0.05);④右、左肺动脉之间比较也有显著性统计学意义(P<0.01);⑤不同的重建方法各有其优越性,其中,MIP重建能较好的显示肺动脉干、右肺动脉左肺动脉,并且其测量值比其它重建方法测量较为准确。结论多层螺旋CT胸部增强扫描,通过工作站三维重建能较好的显示肺动脉干、右肺动脉和左肺动脉,并对其进行科学的评价,这种方法优于传统的尸体解剖方法,其数据可靠,此方法可以对活体人的器官进行大样本的形态学研究。Objective To image human pulmonary trunk,right pulmonary artery and left pulmonary artery with multislice spiral CT and measure and evaluate pulmonary trunk and right pulmonary artery and left pulmonary artery.Methods 340 normal cases were chose to do the chest enhanced multi-slice spiral CT scan and the images were transmitted to workstation to make a three-dimensional reconstruction.Observing and measuring the pulmonary trunk,right pulmonary artery and left pulmonary artery,and then made analysis for the pulmonary trunk,right pulmonary artery and left pulmonary artery.Results ① Spiral CT scanning and imaging measurement of pulmonary artery diameter is smaller than the X-ray measurement of the pulmonary artery diameter and it has statistic significance (P<0.05);② The diameter of pulmonary artery were also significantly different between male and female (P<0.05);③ There are differences between the different aging groups for the pulmonary artery (P<0.05);④ There was significant statistic difference the right between left pulmonary artery (P<0.01) ⑤ Different reconstruction methods have their own superiority,in which,MIP reconstruction can show the pulmonary trunk,left pulmonary artery from right pulmonary artery better than others and its measuring value is more accurate.Conclusion The chest enhanced multi-slice spiral CT scan can display the pulmonary trunk,right pulmonary artery and left pulmonary artery better through threedimensional reconstruction in the workstation than the conventional autopsy method and make a scientific evaluation.Its data is reliable,this method could be used in morphological study with a large scale sample for the organs in living body.
