64排螺旋CT成像与DSA在冠心病诊断中的应用分析

Application of 64-slice Spiral CT and DSA in the Diagnosis of Coronary Artery Disease

目的探讨64排螺旋CT对于冠心病的诊断价值。方法随机选取2014年1月—2015年11月期间该院收治的选择性冠脉造影确诊为冠心病的患者34例,对其进行64排螺旋CT扫查,并对结果进行分析。结果该次研究中,CTA和DSA在不同程度冠状动脉狭窄病变的检出率方面差异无统计学意义(P>0.05),其中CTA对于冠心病诊断的特异性为98.16%,敏感性96.33%,阴性预测值97.56%,阳性预测值97.22%;34例患者共计受检136节段血管,其中102节段存在可见钙化病变,检出率为75.00%。结论64排螺旋CT冠脉成像是一种可靠、简便的冠心病无创检查方法,可有效地对冠状动脉主要血管中的病变进行清晰显示,在冠心病诊断方面具有较高的准确性,特别是其无创特性及较高的钙化病变灶检出率同冠脉造影相比具有显著优势,建议在临床进一步推广。

Objective Explore the diagnostic value of 64-slice spiral CT for coronary heart disease. Methods Randomly selected in January 2014 — November 2015 admitted to hospital during selective coronary angiography in 34 patients diagnosed with coronary artery disease, its 64-slice spiral CT scanning, and the results were analyzed. Results In this study,CTA and DSA no significant difference（P 〉0.05）, in varying degrees of coronary artery lesion detection rate, wherein the CTA for the diagnosis of coronary heart disease specificity of 98.16%, 96.33% sensitivity and negative predictive value97.56%, positive predictive value of 97.22%; 34 patients examined a total of 136 vascular segments, 102 segments visible presence of calcified lesions, the detection rate of 75.00%. Conclusion 64-slice spiral CT coronary angiography is a reliable, simple and noninvasive method of coronary heart disease can be effectively main coronary artery lesions in a clear display with high accuracy in the diagnosis of coronary heart disease, especially in its noninvasive characteristics and higher detection rates with calcified lesions in coronary angiography compared stove has a significant advantage, it is recommended to further promote clinical.
