目的:探讨双源CT(DSCT)评价粥样硬化斑块的应用价值。方法:对100例急性冠状动脉综合征患者进行血管内超声和DSCT检查。结果:DSCT诊断斑块的敏感性、特异性、阳性预测值、阴性预测值分别为89.94%、98.32%、96.09%和95.52%;诊断软斑块的敏感性、特异性、阳性预测值、阴性预测值分别为92.83%、93.33%、97.78%和80.46%。结论:DSCT对诊断粥样硬化斑块具有较高的敏感性、特异性、阳性预测值和阴性预测值,可有效区分斑块的性质。
Objective: To evaluate the value of double-source computed tomography (DSCT) in the evaluation of atherosclerotic plaques. Methods: One hundred patients with acute coronary syndrome were examined by intravascular ultrasound and DSCT. Results: The sensitivity, specificity, positive predictive value and negative predictive value of DSCT were 89.94%, 98.32%, 96.09% and 95.52%, respectively. The sensitivity, specificity, positive predictive value and negative predictive value of soft plaque The predicted values were 92.83%, 93.33%, 97.78% and 80.46% respectively. Conclusion: DSCT has high sensitivity, specificity, positive predictive value and negative predictive value for the diagnosis of atherosclerotic plaques, which can effectively distinguish the nature of plaque.
