摘　　要：目的探讨双低剂量多层螺旋CT血管成像(MSCTA)在咯血患者行栓塞术前的评估价值。方法回顾性分析39例咯血患者"双低"(低对比剂剂量、低辐射剂量)剂量支气管动脉CT血管成像(CTA)检查和常规数字减影血管造影(DSA)检查,并分成CTA组和DSA组进行对比研究。结果 CTA检查与术中DSA检查分别显示支气管动脉为104支和107支。以DSA检查结果为标准,CTA检出的正常起源支气管动脉、异常起源支气管供血动脉、由支气管动脉供血的异常肺内病灶,符合率分别为100%、89%、100%。结论 "双低"剂量支气管动脉MSCTA对支气管动脉检出的敏感度高、对侧支供血动脉显示效果理想,并能清晰显示肺内病灶,而且可大幅降低辐射剂量,患者舒适度相对提高。Objective To investigate the diagnostic value of dual-low dose bronchial arterial multislice computed tomography angiography (MSCTA) in hemoptysis patients underwent therapeutice mbolization preoperatively. Methods A retrospective analysis of 39 cases of hemoptysis patients was carried out. Enrolled patients received dual- low dose (low dose of contrast agent and low dose of radiation dose) bronchial artery CT angiography(CTA) examination and routine digital subtraction angiography(DSA)examination,and were further divided into CTA group and DSA group to make a comparative study. Results There were 104 and 107 branches of the bronchial arteries found by CTA examination and intraoperative DSA examination,respectively. With the findings of DSA as standard,the diagnostic coincidence rates of CTA detected bronchial arteries of normal origin,minor feeding arteries of anomalous origin,and anomalous pulmonary lesions supplied by the bronchial artery were 100%,89% and 100%,respectively.Conclusion Dual -low dose bronchial arterial MSCTA examination has high sensitivity in detecting bronchial artery,and ideal enhancement effect of the collateral feeding artery that can clearly display lesions in the area of the pulmonary. Radiation dose in patients with dual-low dose bronchial arterial CTA examination is considerably lower than that of DSA. The patient′ s comfort is improved.
