摘　　要：目的:探讨螺旋CT血管造影(CTA)与动态增强磁共振血管造影(DCE-MRA)在胸腹部大血管疾病诊断中的应用价值。方法:选取在医院进行治疗的32例胸腹部大血管疾病患者,对所有患者均行CTA和DCE-MRA检查,将两种检查方法所得原始图像进行后处理,对比分析图像质量评分,并对两种检查的诊断符合率进行对比评价。结果:两种检查方法均一次成功,对病变的定位及与周围血管的关系均可明确判断。32例患者中CTA图像质量评分为3分、2分和1分者分别为30例(占93.75%)、2例和0例;DCE-MRA评分分别为31例(占96.87%)、1例和0例,两种检查方法图像质量优良率比较,差异均无统计学意义(x^(2)=0.356,P>0.05)。CTA诊断符合率为96.88%(31/32),漏诊1例,误诊0例;DCE-MRA诊断符合率为96.88%(31/32),漏诊1例,误诊0例;两种检查方法的诊断符合率相比无差异。结论:CTA和DCE-MRA在胸腹部大血管疾病诊断中均有较好的应用价值,CTA检查过程快速、扫描范围大,分辨率高;DCE-MRA图像质量较好且造影方式更安全。Objective:To investigate the application values of spiral computed tomography angiography(CTA)and dynamic contrast-enhanced magnetic resonance angiography(DCE-MRA)in diagnosing the thoracic and abdominal large vessel diseases.Methods:A total of 32 patients with thoracic and abdominal large vessel diseases who admitted to hospital were selected.All patients underwent spiral CTA and DCE-MRA examinations.The original images obtained from the two examination methods were post-processed,and the scores of image quality were compared and analyzed,and the diagnostic coincidence rates of the two kinds of examinations was compared and evaluated.Results:Both two kinds of methods were one-time success,and the location of the lesions and the relationship between that and the peripheral blood vessels could be clearly judged.The numbers of 3 scores,2 scores and 1 score of CTA image quality were respectively 30 cases(93.75%),2 cases and 0 case.The numbers of DCE-MRA scores were respectively 31 cases(96.87%),1 case and 0 cases.There was no significant difference in the excellent rate of image quality between the two kinds of methods(x^(2)=0.356,P>0.05).The coincidence rate of CTA diagnosis was 96.88%(31/32),with 1 case missed diagnosis and 0 case misdiagnose.The coincidence rate of DCE-MRA diagnosis was 96.88%(31/32),with 1 case missed diagnosis and 0 case misdiagnose.There was no significant difference in diagnostic coincidence rate between the two kinds of methods.Conclusion:Both CTA and DCE-MRA have better application values in diagnosing the thoracic and abdominal large vessel diseases.The process of CTA examination is fast,and the scanning range of that is large,and the resolution of that is high.DCE-MRA has better image quality,which imaging method is safer.
