摘要
目的：探讨多层螺旋CT(multi-slice computer tomography，MSCT)在急诊胸痛患者诊断中的临床价值。方法：对本院急诊收治的162例胸痛患者进行MSCT平扫、增强扫描和血管造影成像，并对数据进行容积再现、曲面重组、多平面重组、最大密度投影等方法观察冠状动脉、主动脉、肺动脉。结果：急诊收治的162例胸痛患者中，所有患者可以清晰显示冠状动脉左右主干及主要分支、胸主动脉以及肺动脉段以上分支。发现冠状动脉狭窄者129例(79.6%)，主动脉夹层18例(11.1%)，肺动脉栓塞15例(9.3%)。结论：多层螺旋CT能够一次性完成对常见胸痛病因的鉴别诊断，迅速提供清晰、高质图像，是急诊胸痛患者的理想影像学检查方法。

Abstract
Objective: To explore the diagnostic value of multi-slice computer tomography (MSCT) in evaluating patients with chest pain at emergency room. Methods: 162 patients with chest pain admitted at emergency room were recruited for this study. All patients received scan, contract enhanced scan and angiography by MSCT. Raw data of MSCT were further processed by volume rendering, curved planar reformation, multiplanar reconstruction, and maximum intensity projection to evaluate the status of coronary artery, aortic artery and pulmonary artery. Results: The coronary artery and major branches, thoracic aorta, and branches above pulmonary artery segment of all patients could be clearly demonstrated. Among 162 patients, 129 were diagnosed as coronary artery stenosis (79.6%), 18 were determined as aortic dissection (11.1%), and 15 were identified as pulmonary artery embolism (9.3%). Conclusion: MSCT can provide high-quality images for differentiation diagnosis of major causes of chest pain at emergency room. Hence, MSCT can be considered as an ideal diagnosis approach of emergent chest pain.
