目的:比较64排螺旋CT(64SCTCA)冠状动脉成像和冠状动脉造影对冠心病的诊断价值。方法:对36例患者均采用64SCTCA与选择性冠状动脉造影检查分析冠状动脉,并进行对比分析。结果:64SCTCA诊断冠状动脉病变的敏感性为85%,特异性为89%,阳性预测值85%,阴性预测值91%。结论:64SCTCA作为无创的检查在显示冠状动脉病变时,具有较高的敏感性和特异性,对于预测及早期诊断冠心病,有重要的临床应用价值。
Objective: To compare the diagnostic value of 64-slice spiral CT (64SCTCA) coronary angiography and coronary angiography in coronary heart disease. Methods: Sixty-six patients underwent coronary angiography with 64SCTCA and selective coronary angiography. The coronary arteries were analyzed and compared. Results: The sensitivity of 64SCTCA in diagnosing coronary artery lesions was 85%, the specificity was 89%, the positive predictive value was 85% and the negative predictive value was 91%. Conclusion: As a noninvasive examination, 64SCTCA has high sensitivity and specificity in displaying coronary artery lesions. It has important clinical value for predicting and early diagnosis of coronary heart disease.
