摘　　要：目的探讨宝石能谱CT高分辨重建模式成像对提高冠状动脉支架显示的应用价值。方法选取28例冠状动脉支架术后CT复查的患者为观察对象,使用宝石能谱CT进行冠状动脉CTA扫描后,对所有受检者的原始数据分别进行高分辨率模式重建和标准模式重建,观察支架腔及支架壁的显示能力。结果高分辨模式重建组的冠状动脉支架成像质量主观评分优于标准重建组,差异有统计学意义(P<0.05);高分辨模式重建组的冠状动脉支架内径、支架管腔显示率优于标准重建组,支架内CT值增加值明显低于常规扫描组,差异有统计学意义(P<0.05)。结论宝石能谱CT高分辨重建模式能够清楚的显示支架内特点,可明显提升冠脉支架成像质量,具有良好的临床应用价值。Objective To investigate the value of Gemstone spectral CT high resolution reconstruction mode imaging in improving coronary stent display.Methods Twenty-eight patients who underwent CT reexamination after coronary stenting were selected as the observation objects.After coronary CTA scanning with gemstone spectral CT,high-resolution mode reconstruction and standard mode reconstruction were performed respectively on the original data of all patients to observe the display ability of stent lumen and stent wall.Results The subjective assessment of coronary stent imaging quality in the highresolution mode reconstruction group demonstrated superior performance compared to the standard reconstruction group.This difference was found to be statistically significant(P<0.05).The coronary stent diameter and stent lumen display rate in the high resolution mode reconstruction group were better than those in the standard reconstruction group,and the increase of CT value in the stent was significantly lower than that in the conventional scanning group,and the differences were statistically significant(P<0.05).Conclusion Gemstone spectral CT high-resolution reconstruction mode can clearly display the characteristics of the stent,can significantly improve the imaging quality of coronary stent,and has good clinical application value.
