16排螺旋CT在高危胸痛诊断中的应用

目的:通过一次CT扫描同时完成冠状动脉、主动脉和肺动脉CTA检查,鉴别上述高危胸痛,探讨16排螺旋CT在高危胸痛诊断中应用价值。方法:2005年12月~2008年6月住院及急诊胸痛患者46人。应用两种方法行行一次性胸痛三联检查。结果:46例患者一次检查均可清晰显示肺动脉段以上分支、胸主动脉及冠状动脉左右主干及主要分支。共发现冠状动脉狭窄42例,肺动脉栓塞5例,主动脉夹层2例。结论:16排螺旋CT一次动脉期增强扫描显示肺动脉、胸主动脉及冠状动脉,对胸痛病因的诊断及鉴别诊断具有重要意义。

Role of 16-slice spiral CT in acute chest pain

Objective：To evaluate the diagnosis and differential diagnosis value of 16-slice spiral CT in high-risk chest pain patients together with application of CTCA,CTPA and aortic CTA examination.Methods：During the period from the 2005,12 to 2008,6,46 inpatients and emergency patients（31 males and 15 females,aged 36～78 years） with chest pain,chest distress and precardial discomfort were investigated.16-slice spiral CT was used.Patients were chest enhanced scanning with two methods.Results：Higher segmental pulmonary artery,thoracic artery,main（left and right） coronary artery and its main branches were clearly shown.There were 42 cases with coronary artery stenosis,5 cases with pulmonary artery embolism,and 2 cases with aortic dissection.Conclusion：Arterial phase dynamic enhanced 16-slice spiral CT scanning shows pulmonary artery,thoracic artery and coronary artery,which is very important for diagnosing and differentially diagnosing the causes of chest pain.
