【摘要】 目的利用多层螺旋 CT(MSCT)探讨病灶最大径<3和≥3 cm 肺癌患者及正常人的支气管动脉内径差异。方法对44例经手术病理证实的肺癌患者资料作回顾性分析,男27例,女17例,年龄19～82岁,中位年龄58岁。其中3 cm 以下的小肺癌15例,≥3 cm 的肺癌29例,所有患者均进行16层螺旋 CT 增强扫描,三维重组支气管动脉,测量支气管动脉的内径。正常对照组,男16例,女12例,年龄22～78岁,中位年龄53岁。对3组支气管动脉内径行方差分析。结果 15例小肺癌支气管动脉内径平均值为(1.9±0.4)mm,29例大肺癌支气管动脉内径平均值为(2.5±0.5)mm,28例正常组支气管动脉内径的平均值为(1.6±0.4)mm,大、小肺癌及正常组之间支气管动脉内径差异有统计学意义(P<0.05)。结论供应肺癌的支气管动脉均增粗,大肺癌较小肺癌显著。更多还原

【Abstract】 Objective To evaluate the difference of internal diameter of bronchial artery in big lung cancer,small lung cancer,and normal lung with multiple slice CT.Methods MSCT angiographies of 44 patients with lung cancer confirmed by pathology were retrospectively analyzed,and 29 patients were with big lung cancer(≥3 cm)and 15 patients with small lung cancer(<3 cm).Contrast enhanced helical thin slice CT scan was performed in all patients.Three dimensional images of bronchial artery were processed on workstation.The internal diameter of bronchial artery was measured.Results The diameter of bronchial artery was(1.9±0.4)mm in 15 small lung cancer and(2.5±0.5)mm in 29 big lung cancer, respectively.There was a significant difference in internal diameter of bronchial artery between big and small lung cancer(P<0.05).Conclusion Bronchial artery in lung cancer is dilated,and the dilation of bronchial artery in big lung cancer is more prominent than in small lung cancer.更多还原
