Abstract

Objective To explore the value of multi-slice spiral CT coronary angiography (MSCTCA) in the evaluation of coronary artery stenosis. Methods 63 cases of patients diagnosed with coronary heart disease underwent MSCTCA and coronary angiography (CAG) at the same time in 1 month. The examination results were compared. Results With CAG as the golden standard, the accuracy, sensitivity and specificity of MSCTCA in diagnosis of coronary artery disease were 92.06%, 95.45% and 84.21%, respectively. The consistency with CAG was very good (Kappa=0.834); 63 cases were with a total of 945 coronary artery segments and 907 segments can be evaluated. The coincidence rate of MSCTCA in diagnosis of coronary artery stenosis degree was 92.94%, and the diagnostic compliance rate with CAG was good (Kappa=0.517); The accuracy rates in the diagnosis of no stenosis, mild stenosis, moderate stenosis and severe stenosis were 93.75%, 82.86%, 90.28% and 92.97%, respectively. Conclusion The accuracy rate of MSCTCA in the diagnosis of coronary artery stenosis and stenosis degree is relatively higher
