螺旋CT成像对左肺上叶段级与亚段级动脉的评价
Evaluation on the segmental and sub-segmental pulmonary artery of the superior lobe in the left lung by spiral CT angiography
摘要
Abstract
Objective-. To explore feasibility of 3D reconstruction of the segmental and sub-segmental pulmonary artery of the superior lobe in left lung adopting multilayer spiral CT and observe and measure caliber. Methods-. Totally 340 "healthy a-dults underwent contrast-enhanced CT angiography of thoracic part using multilayer spiral CT. Different methods of 3D reconstruction were used to observe and measure the caliber of segmental and sub-segmental pulmonary artery of the superior lobe of the left lung. Statistical analysis were carried out among all cases which were divided into two groups by gender and three groups by age (20-40 year, 41-60 year, 61-87 year). Results-. There were significant differences in the pulmonary artery caliber between male and female and among age groups. Different reconstruction methods had their own advantages. MIP and STS-MIP reconstruction can be better for showing segmental and sub-segmental pulmonary artery, which were more accurate. Conclusion-. 3D reconstruction based on enhanced scanning image of multilayer spiral CT can be better for displaying and evaluating each segmental of pulmonary artery. Large sample measurement also can be undertaken, which provides theoretical data for clinical diagnosis of pulmonary difficult-and-rare-case.关键词
