【摘要】 目的探讨基于对比剂线性模型法的支气管动脉CTA在咯血介入治疗术前诊断中的价值。方法 80例咯血患者行基于对比剂线性模型法的支气管动脉CTA,测量靶血管CT值评估血管成像质量,同时52例患者与DSA比较支气管动脉检出符合率。结果靶血管中支气管动脉CT值大于200 HU,高于周围脏器实质。CTA检出支气管动脉100支(其中3支DSA未检出);DSA检出支气管动脉106支(其中9支CTA未检出),检出一致率为91.5%。二者对常位、异位支气管动脉的检出能力无统计学差异。结论基于本研究中对比剂线性模型法的支气管动脉CTA具有良好的血管成像质量,且支气管动脉检出率与DSA有较高一致性,可作为咯血患者支气管动脉栓塞术前评估的常规检查。更多还原

【Abstract】 Objective To investigate the value of contrast-based linear modeling method of bronchial artery CTA in the preoperative diagnosis of hemoptysis interventions. Methods In 80 patients with hemoptysis, CTA of bronchial arteries was performed based on the contrast linear model method, and the CT values of target vessels were measured to assess the quality of angiography, while 52 patients were compared with DSA for bronchial artery detection compliance. Results The bronchial arteries in the target vessels had CT values greater than 200 HU, higher than the surrounding organ parenchyma. 100 bronchial arteries were identified by CTA(3 of which were not detected by DSA), 106 bronchial arteries were detected by DSA(9 of which were not detected by CTA), and the detection agreement was 91.5%. There was no statistical difference between CTA and DSA in the ability to detect normal and ectopic bronchial arteries. Conclusion The bronchial artery CTA based on contrast linear model method in this study has good angiographic quality and a high concordance between bronchial artery detection rate for preoperative evaluation of bronchial artery embolization in patients with hemoptysis.更多还原
