摘　　要：目的利用多层螺旋CT测量活体右肺下叶肺段与亚肺段动脉管径的数值范围，为肺动脉病变的影像学诊断提供参考数据。方法选择274例无心肺疾病患者，行胸部cT增强扫描，按性别分男、女两组；按年龄（20～40岁、41～60岁、61岁以上）分3组，在最大密度投影（MIP）图像上测量右肺下叶肺段和亚段肺动脉管径的数值，并进行男、女两组及不同年龄组肺段与亚段肺动脉管径的比较分析。结果在MIP图像上能准确测量右肺各肺段及亚肺段肺动脉管径的数值，男、女性右肺下叶各肺段、亚肺段动脉管径比较，差异有显著性意义（P〈0．05）；男、女各年龄组肺段与亚肺段动脉管径比较，差异有显著性意义（P〈0．05），尤其是20—40岁与61-85岁的年龄组之间。结论多层螺旋CT能清楚地显示右肺下叶肺段及亚肺段动脉是测量肺段和亚肺段动脉管径值的有效方法。Objective To measure the numerical value of segmental and sub-segmental pulmonary arteries of the right inferior lobe by multislice spiral CT angiography, to provide reference data for the imageology diagnosis of lung arteriopathy. Methods Totally 274 patients with no cardiac pulmonary diseases were performed with thoracic enhanced CT scans. The patients were divided into gender groups and three age groups of 20-40 year,41-60 year,and above 60 year. The diameter of segmental and sub-segmental pulmonary arteries of the right inferior lobe on the MIP images were observed, measured, compared and analyzed between the gender groups and among age groups. Results The numerical value of the diameter of segmental and sub-segmental pulmonary arteries of the right lung was accurately measured on the MIP images. There were significant differences of the diameter of segmental and sub-segmental pulmonary arteries of the right inferior lobe between the male and the female groups（ P 〈 0.05 ）. There were significant differences of the diameter of segmental and sub-segmental pulmonary arteries between the gender groups and among age groups （P 〈 0.05 ） , especially between the age groups of 20-40 year and 61-85 year. Conclusion The imaging of multislice spiral CT can clearly display segmental and sub-segmental pulmonary artery of the right inferior lobe. It is reliable to measure the segmental and sub-segmental pulmonary arteries.
