【摘要】 目的:通过和冠脉造影对比,评价64排螺旋CT冠状动脉成像在冠状动脉狭窄中的临床应用价值。方法:28例患者同时行64排螺旋CT冠状动脉成像和有创性冠脉造影检查,依据AHA17段分段法,评价所有有效节段,并将两者进行对比。结果:冠脉造影显示阴性病例占7.1%(2例),单只病变占21.4%(6例),多支病变占71.4%(20例)。按节段分析,CT检出冠脉狭窄的敏感度,特异度,阳性预测值和阴性预测值分别为91.1%,94.6%,90.0和95.3%。结论:64排螺旋CT冠状动脉成像和传统的冠脉造影检查对检出正常冠脉节段以及狭窄节段具有很好的一致性。更多还原

【Abstract】 Objective:Compare with invasive coronary angiography,to evaluate the clinical application value of 64-row MSCT(multislice spiral computed tomography)coronary angiography.Methods:28 patients underwent both 64-slice MSCT and invasive coronary angiography,all available coronary segments using a 17-segment modified AHA classification were included in the evaluation,and the results of the both methods were compared.Results:Coronary angiography demonstrated normal arteries in 7.1%(2 of 28),single-vessel disease in 21.4%(6 of 28),and multi-vessel disease in 71.4%(20 of 28) of patients.Sensitivity,specificity,positive and negative predictive values for detection of significant lesions on a segment-based analysis were 91.1%,94.6%,90.0 and 95.3%.Conclusion:64-row MSCT coronary angiography and invasive coronary angiography were correctly identified in evaluating normal coronary arteries or significant stenosis lesions.更多还原
