Abstract

Abstract:

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.
