摘要
目的:探讨64排螺旋CT三联CTA检查在急性胸痛中的诊断价值。材料与方法:58例急性胸痛患者行螺旋CT三联CTA检查,对患者原始图像进行后处理,包括多平面重建(MPR)、曲面重建(CPR)、容积再现(VR)及最大密度投影(MIP)等方法显示冠状动脉、胸主动脉及肺动脉,2名高年资放射科医师对图像进行观察、诊断。结果:患者一次检查可显示冠状动脉、胸主动脉、肺动脉主干及其主要分支、并能观察肺窗、纵隔窗图像。其中肺动脉栓塞10例,冠状动脉斑块形成、管腔狭窄22例,主动脉夹层8例,气胸10例,体-肺动脉分流1例,7例未见异常。结论:64排螺旋CT三联CTA检查一次扫描能显示冠状动脉、肺动脉以及胸主动脉,还能显示肺部疾病,是急性胸痛病因诊断无创、可靠的检查方法。
Purpose： To explore the value of ＂triple rule out＂ CTA using 64-MDCT in acute chest pain. Materials and Methods： fifty-eight patients with acute pains were performed 64-spiral CT chest angiography. Two-dimensional and three-dimensional reconstruction was performed in all patients by means of muhiplanar reconstruction（MPR） , curved planar reformation（CPR）, volume rendering（VR）, and maximum intensity projection （MIP）. All images were blindly reading by two experienced radiologist. Results： the coronary artery branches, pulmonary artery and aortic artery in all patients were showed clearly. The pulmonary artery embolism were showed in 10 cases, the acute myocardial infarction in 22cases, the aor- tic dissection in 8 cases, pneumothorax in 10 cases, systemic-to-pulmonary artery in one case, normal findings in 7 cases. Conclusion： ＂Triple rule out＂ CTA using 64-MDCT is a useful and noninvasive examination in acute pain.
