摘要:
目的:探讨新双源CT Flash扫描技术行冠状动脉CT血管成像(CTA)对冠状动脉狭窄的诊断价值。方法:回顾性分析52例行Flash CTA且同时行冠状动脉造影(CAG)的患者的影像学资料。结果:Flash CTA对冠状动脉狭窄病变诊断的敏感性、特异性、阳性预测值、阴性预测值和约登指数分别为84.3%、95.7%、89.7%、93.2%和080;有效辐射剂量为(0.98~1.15) mSv。Flash CTA与CAG对冠状动脉狭窄程度分级的一致性较好(Kappa=0888,P<0.001)。结论:Flash CTA有效辐射剂量低,对冠状动脉狭窄的诊断,尤其是对中、重度冠状动脉狭窄具有较高的应用价值。
Abstract:
Aim:To evaluate the value of dualsource Flash CT angiography(Flash CTA) in the assessment of coronary artery stenosis diseases.Methods:The results of Flash CTA and coronary artery angiography(CAG) from 52 patients were retrospectively reviewed.Results:The diagnosis sensitivity,specificity,positive predictive value,negative predictive value and Youde index of coronary artery stenosis with Flash CTA were 84.3%,95.7%,89.7%,93.2%,and 0.80,respectively.And the effective radiation dose was (0.98~1.15) mSv.The result of Flash CTA was well agreed with CAG(Kappa=0888,P<0.001).Conclusion:Flash CTA with a low effective radiation dose,is valuable for the diagnosis of coronary artery stenosis,especially for moderate and severe stenosis.
