目的探讨螺旋CT冠脉成像(CTA)与冠脉造影(CAG)对冠心病诊断的价值。方法选取本院2005年2月到2010年1月中住院或已确诊冠心病患者280例,同时做了螺旋CT冠状动脉成像检查和冠状动脉造影检查的患者。结论 280例患者均获得良好的三维重建,CTA诊断冠心病灵敏度为64.3%,特异度为92.1%,阳性预测值为89.77%,阴性预测值为97.90%。在显示冠状动脉狭窄分级方面具有良好的一致性。结论螺旋CT冠脉成像是一种安全、简便、无创、经济较为可靠的冠脉病变无创检查方法,在冠状动脉造影中具有良好的发展前景,对冠脉主要血管的中、重度狭窄病变冠状动脉疾患的筛选,开口变异,对钙化病变诊断率优于冠脉造影,为临床治疗及无创筛选提供可靠的诊断依据。
Objective To investigate the value of spiral CT coronary angiography (CTA) and coronary angiography (CAG) in the diagnosis of coronary heart disease. Methods Two hundred and eighty patients were hospitalized or diagnosed as coronary heart disease from February 2005 to January 2010 in our hospital. At the same time, we performed spiral CT coronary angiography and coronary angiography. Conclusion All 280 patients achieved good 3D reconstruction. The sensitivity, specificity and accuracy of CTA in diagnosing CHD were 64.3%, 92.1%, 89.77%, and 97.90%, respectively. Good consistency in showing grade of coronary artery stenosis. Conclusion Coronary CT angiography is a safe, simple, noninvasive and reliable noninvasive method of coronary artery disease. It has a good prospect in coronary angiography, Disease screening, opening variation, the diagnosis of calcification lesions than coronary angiography, for clinical treatment and noninvasive screening provide a reliable basis for diagnosis.
