| 摘要 目的：探讨宝石能谱CT用于冠状动脉支架内成像质量评估的应用价值。方法：回顾分析56例冠状动脉支架植入后患者，按照支架厚度及直径分成四组。采用宝石能谱CT对冠状动脉成像及同时进行冠状动脉造影患者的影像学资料，通过分析宝石能谱CT的冠状动脉的成像质量，与冠状动脉造影进行对比，得出宝石能谱CT用于冠状动脉介入治疗术后支架内成像质量评估的价值。结果：宝石能谱CT显示支架内再狭窄的敏感度为100 %，特异度为98.6 %，阴性预测值为100 %。直径≥3 mm的支架内成像质量优于直径<3 mm的支架。但支架直径和厚度对宝石能谱CT支架内成像质量的可评估率没有差异。结论：宝石能谱CT均能提供优秀的冠状动脉支架内成像质量，采用宝石能谱CT替代冠状动脉造影术可对冠脉支架术后支架内影像进行评估。 |

| ABSTRACT Objective: To explore the application value of gemstone energy spectrum CT for evaluating the quality of coronary stent imaging. Methods: The imaging data of 56 patients after coronary artery stent implantation were retrospectively analyzed. The study group was divided into four groups according to the thickness and diameter of the stent. By analyzing the imaging quality of coronary artery with gemstone energy spectrum CT and comparing with coronary angiography, the value of gemstone energy spectrum CT in eval- uating the quality of in-stent imaging after percutaneous coronary intervention. Results: The sensitivity, specificity and negative predic- tive value of in-stent restenosis of gemstone energy spectrum CT were 100 %, 98.6 % and 100 %, respectively. IQ score for stent diame- ter ≥3 mm was significantly higher than that for stent diameter <3 mm for stents with both thick struts and thin struts. However, there is no difference in the evaluation rate of in-stent imaging quality between the diameter and thickness of the stent. Conclusion: Gemstone en- ergy spectrum CT can provide excellent in-stent imaging quality. Gemstone energy spectrum CT can be used to evaluate in-stent imaging after coronary stenting instead of coronary angiography. |
