摘　　要：目的:探讨64排螺旋CT胸痛三联检查在急性胸痛病因诊断中的临床价值。材料和方法:对65例胸痛患者行64排螺旋CT胸痛三联检查,所有患者原始数据行多平面重建(MPR)、容积再现(VR)、曲面重建(CPR)、最大密度投影(MIP)等方法分别进行冠状动脉、肺动脉、主动脉成像,由2名有经验的放射科医师进行诊断。其中22例患者行选择性冠状动脉造影检查,并与64排螺旋CT冠状动脉CTA结果相对照。结果:所有行64排螺旋CT检查的患者均可清晰显示双侧肺动脉、冠状动脉主干及其主要分支以及胸主动脉。显示肺动脉栓塞21例、冠状动脉狭窄30例、主动脉夹层8例、主动脉瘤2例、气胸1例、3例未见明显异常。结论64排螺旋CT胸痛三联检查扫描在急性胸痛病因诊断中具有较高的临床应用价值,是一种无创、准确、快速的检查方法。Objective： To explore the clinical value of 64-MDCT chest angiography protocol for diagnosis of chest pain. Methods： Sixty-five patients with chest pain were performed 64-MDCT chest angiography. Two-dimensional and three-dimensional reconstruction was performed in all patients by means of multiplanar reconstruction（MPR）, curved planar reformation（CPR）, maximum intensity projection（MIP）, and volume rendering（VR）. All images were blindly reading by two experienced radiologist, DSA were performed at the same time in 22 cases. Results： The coronary artery branches, pulmonary artery and aortic artery in all patients were showed clearly. The significant coronary artery stenosis were showed in 30 cases, The pulmonary artery embolism in 21 cases, The aortic dissection in 8cases, the aortic aneurysm in 2 cases, respectively, The pneumothorax in one case. Normal fmdings in 3 cases. Conclusion 64-MDCT chest angiography has high clinical value and is a useful and noninvasive examination in the differential diagnosis of chest pain.
