胸痛三联征128层螺旋CT扫描观察应用

目的:分析128层螺旋CT扫描技术在胸痛三联征中的优化应用价值。方法:对临床高度怀疑胸痛三联征的69例患者，行急诊128层螺旋CTA检查，对所有病例原始数据进行最大密度投影（MIP）、曲面重建（CPR）、容积再现（VR）、多平面重建（MPR）等多种后处理技术重建，分别对胸主动脉、冠状动脉以及肺动脉进行不同角度成像分析。结果:69例急性胸痛患者均可清晰显示胸主动脉和双侧肺动脉主干及分支（CT值≥ 200 HU）；同时冠状动脉显影图像质量优占63.7.0%（44/69），良占30.4%（21/69），差占5.8%（4/69）。结论:128层螺旋CTA三联扫描CTA检查对冠脉综合征诊断特异性为94.7%（36/38），准确性为95.8%（69/72）；对肺动脉和主动脉病变诊断的特异性和准确性非常高。通过这一研究结果可初步断定128层螺旋CT三联扫描技术在胸痛三联征中具有重要的应用价值。 

Chest Pain Triad 128-slice Spiral CT Scanning Imaging Application

Objective: to analyze and optimize the application value of 128 slice spiral CT scanning in chest pain triad. Methods: 69 patients with highly suspected chest pain triad were examined by 128 slice spiral CTA, and all the original data were reconstructed with a variety of post-processing techniques such as maximum density projection (MIP), surface reconstruction (CPR), volume rendering (VR), and multiplane reconstruction (MPR).The methods were performed on the thoracic aorta and coronary artery respectively. The arteries and pulmonary arteries were analyzed at different angles. Results: the main branches of the thoracic aorta and bilateral pulmonary arteries (CT value of 200 HU) were clearly shown in 69 patients with acute chest pain, and the image quality of the coronary artery was superior to 63.7% (44/69), 30.4% (21/69) and 5.8% (4/69). Conclusion: the specificity of the 128 slice spiral CTA triple scan CTA examination in the diagnosis of coronary syndrome is 94.7% (36/38), the accuracy is 95.8% (69/72). The specificity and accuracy of the diagnosis of the pulmonary artery and the aortic disease is very high. Through this study, we can preliminarily conclude that 128 slice spiral CT triple scanning has important application value in the triplet of chest pain.
