冠脉支架植入术已成为一项成熟的冠心病诊疗手段,但有近45%的冠脉支架会出现支架内再狭窄。传统的64排CT因受空间分辨率和对比分辨率相对较低的限制,对冠脉支架的成像效果不尽人意。我院引进宝石能谱CT后因其具有较高的分辨率,成像效果大大提高,基本达到了临床诊断的需要。现就收集的两组病例对比分析如下。
Coronary stent implantation has become a mature treatment of coronary heart disease, but nearly 45% of coronary stent restenosis will occur. Due to the relatively low spatial resolution and contrast resolution, the traditional 64-slice CT has unsatisfactory imaging results for coronary stents. Our hospital imported gem energy spectrum CT because of its high resolution, imaging results greatly improved, basically reached the needs of clinical diagnosis. The two cases are now collected comparative analysis is as follows.
