目的探讨西门子64排螺旋CT对冠状动脉狭窄病变患者的临床应用价值。方法2014年8月—2015年9月期间,选取该院经临床诊断或疑似冠状动脉狭窄病变的136例患者为研究对象,首先对其进行64排螺旋 CT冠状动脉成像诊断,然后进行传统冠状动脉造影检查,比较两种诊断方法的准确率及精密度。结果 对冠状动脉狭窄情况,64排螺旋CT冠状动脉成像与冠状动脉造影相比,差异无统计学意义(P>0.05)。64排螺旋CT对冠状动脉狭窄诊断的敏感度为91.19%,阳性率为 66.18%,钙化病变的敏感度为 85.0%,阳性率为 60.29%。结论西门子64排螺旋 CT对冠状动脉狭窄诊断能力较强,具有准确率高,定位准确,检查无创等有点可以作为一种对冠心病进行有效诊断的理想检查方式,值得在以后的临床工作中广泛应用。

[Abstract]Objective To investigate Clinical Application value of Siemens64-slice spiral CT on patients with coronary artery stenosis disease.Methods During the periodofAug 2014-Sep2015,136 patients suspected with coronary artery stenosis lesions were selected as research subjects.According to their clinical data,64-slice spiral CT coronary artery imaging diagnosis and conventional analysis wererespectively conducted.Their diagnostic accuracy and precision were also compared and analyzed.Results When compared to coronary angiography,the differences in manifestations of 64-slice spiral CT coronary artery imaging on conditions of coronary artery stenosis showed no differences(P>0.05).The sensitivityand positive rat of 64-slice spiral CT coronary artery imaging in the diagnosis of coronary artery stenosis were 91.19%and 66.18%,and indexe of calcified lesions were 85.0%and 60.29%respectively.Conclusion Siemens 64-slice spiral CT in the diagnosis of coronary artery stenosis ability,with high diagnostic accuracy,accurate,non-invasive inspection,etc.have little noninvasive,accurate positioning advantages and can be used as a diagnostic for coronary heart disease over check for a valid diagnosis way,it is worth in the future clinical work widely.

近年来,随着人民生活水平的提高,工作、生活压力的增大以及生活作息的不规律等,使得冠心病的发病率呈现一种不断上升的趋势,而该病对患者的生活质量、心理甚至生命安全造成了严重的不良影响及威胁[1-2]。冠状动脉狭窄大多是由动脉粥样硬化引起的[3]。近年来,随着多层螺旋 CT技术的不断发展,冠状动脉 CT引起了医学领域广泛的关注[4-5]。该文以 2014年8月—2015年9月期间收治的136例冠状动脉狭窄病变的患者作为研究对象,探讨64排螺旋CT技术在该病中的临床应用价值,现报道如下。……
