应用多排螺旋CT三联合扫描检查急性胸痛的探讨

The value of multi-slice CT chest three-in-one scan in examination of acute chest pain

目的探讨40排螺旋CT胸部"三联合"扫描在急性胸痛检查中的应用。方法利用西门子40排螺旋CT进行胸部"三联合"增强扫描,38例获得原始横断面图像后,采用容积再现(VR)、最大密度投影(MIP)、多平面重建(MPR)技术处理图像,24例与DSA结果进行比较。结果所有病例CT三联合扫描一次检查均获成功,显示冠状动脉狭窄18例,闭塞1例;急性肺动脉栓塞4例;主动脉夹层2例。结论40排螺旋CT胸部一次扫描获得冠状动脉、主动脉及肺动脉重建图像,对于诊断冠心病、主动脉夹层、肺动脉栓塞等导致急性胸病的常见疾病是一种方便可靠的无创检查方法,具有重要临床应用价值。

Objective to study the value of 40-slice spiral CT chest three-in-one scan in examination of acute chest pain. Methods The original enhanced axial CT image of 38 patients were obtained with Siemens 40-slice spiral CT, and the images were then reconstructed on the extended brilliance workspace with VR, maximum intensity projection and MPR respectively. Among the 38 patients, 24 underwent DSA, and the results were compared with that of CTA. Results All three-in-one scan examination obtained success. The acute myocardial infarction were showed in 18 cases, coronary artery occlusion was showed in 1 case. Pulmonary artery embolism. Was found in 4 cases, and aortic Dissection in 2 cases. Conclusion 40-slice spiral CT chest one scan can timely and accurately sieve patients with chest pain suffered from whether coronary arteries or othey acute severe lesions, and is an accurat and non-invasive technique promising important clinical practice value.
