Applied Value of Gemstone Spectral CT Imagine on Coronary Stents

  • 摘要: 目的:探讨宝石CT对冠脉支架的临床应用价值。方法:收集45例冠脉支架置入术后患者的宝石CTA数据,测量支架内腔的实际直径,比较支架内腔CT值与邻近血管腔CT值的差异。结果:共60枚支架,均显示清晰、无术后狭窄。当支架实际内腔直径≥2 mm时,支架内腔CT值测量稳定性较好,支架内腔CT值与邻近血管腔CT值无明显统计学差异。支架内腔直径<2 mm时,支架内腔CT值测量稳定性差、测量不准确,但是仍能部分观察支架内腔情况。结论:宝石CT冠脉CTA成像,对冠脉支架内腔直径≥2 mm者诊断较理想,对支架内腔直径<2 mm者仍有一定诊断价值。
    Abstract: Objective: To investigate the application value of Gemstone spectral CT in coronary stents. Methods: CTA data of 45 patients with coronary stent implantation were collected, and the actual diameter of stent lumen was measured, and the difference of CT value between the stent lumen and adjacent vascular cavity was compared. Results: a total of 60 stents were found, which showed clear and no stenosis. 1, when the actual stent lumen diameter ≥ 2 mm, the stent lumen CT value measurement with good stability, the stent lumen CT value had no significant difference with the adjacent vascular cavity CT. 2, stent lumen diameter < 2 mm, the measurement of CT value of stent lumen is not stable and inaccurate, MPR images can still partially observe the stent lumen. Conclusion: Gemstone spectral CT has a higher diagnostic value for stents with a diameter ≥ 2 mm, and a definite diagnostic value for stent lumen diameter < 2 mm.
