| 摘 要： | 目的 探讨16层螺旋CT数字减影术在颈部动脉血管成像的应用价值.资料与方法 52例拟诊颈部动脉病变患者,分别采用减影术(computed tomography digital subtraction angiography DS-CTA)及非减影术(computed tomography digital not-subtraction angiography NS-CTA)行三维血管成像,比较两种成像方法的成像时间及图像质量.10例同时接受DSA检查,其中3例为支架置入术后随访,比较DS-CTA与DSA血管成像的一致性.结果 DS-CTA与NS-CTA比较,前者成像时间明显缩短,但两者图像质量差异无统计学意义,DS-CTA能较完整、清晰地显示血管.10例同时接受DSA,结果与DS-CTA一致,3例支架置入术后随访病例均显示管腔通畅,无明显狭窄.结论 16层螺旋CT DS-CTA是一种快速、直观的血管成像技术,可以提供高质量的血管三维重组图像,具有较高的应用价值,可作为临床制定治疗方案的补充手段.

| Abstract: | Objective To investigate the application of 16-slice helical computed tomography digital subtraction in the angiography of carotid arteries. Materials and Methods CT angiography using digital subtraction technique (Computed Tomography Digital Subtraction Angiography DS-CTA) and digital not-subtraction technique (Computed Tomography Digital Not-subtraction Angiography NS-CTA) was performed in 52 patients suspected of lesions. The findings of two techniques were compared. Results DS-CTA took less time than NS-CTA, but there was no significant difference in the image quality between both. Conclusion DS-CTA could be a kind of rapidly direct non-invasive three-dimensional angiography. |
