查询词典 angiography

Results Compared with percutaneous coronary angiography,the sensitivity of sixteen slice sparil CT in diagnosing moderate and severe coronary stenosis was 83.05%,and the specificness,positive predictive value,negative predictive value and degree of accuracy was 95.97%,89.09%,93.46% and 92.31% respectively.

结果 16层螺旋CT冠状动脉造影对照经皮选择性冠状动脉造影对冠状动脉中、重度狭窄显示的对照结果：敏感性83.05%、特异性95.97%、阳性预测值89.09%、阴性预测值93.46%、准确度92.31%。结论 16层螺旋CT冠状动脉造影对心电图正常的胸痛患者具有良好的诊断价值，并可对冠状动脉形态学进行良好的评价，从而进行介入治疗的筛选。
