Abstract:
ObjectiveTo explore the clinical value of 256-slice CT and coronary angiography in the diagnosis of coronary artery disease.Methods46 patients with coronary heart disease,who underwent coronary angiography and 256-slice spiral CT were selected.Compare two methods for the detection of coronary artery disease.Results( 1 ) All 256-slice CT and coronary angiography achieved a satisfactory image,in the diagnosis of coronary artery stenosis and occlusion,the two methods had no statistically significant difference ( P ＞ 0.05 ).(2) according to standard coronary angiography,256-slice spiral CT for the diagnosis of coronary artery stenosis sensitivity was 93.0％ (132/142),specificity was 91.6％ (142/155),positive predictive rate was 91.0％ (132/145),negative predictive rate was 93.4％ (142/152).Conclusion256-slice spiral CT has a high time resolution,spatial resolution,the display of the coronary artery disease has high sensitivity,specificity,positive predictive value and negative predictive value.
