| 摘 要： | 目的：探讨三维重建技术在诊断颅内动脉狭窄中的应用价值。方法：通过对2D DSA和三维重建影像进行对比,来比较血管狭窄处能否正常显示、直径狭窄率和面积狭窄率对血管狭窄程度的精确反映及血管内斑块显示的准确性。结果：2D DSA和三维重建影像在显示颅内狭窄时,无统计学差异,但三维重建影像比二维影像显示更准确,82处狭窄,三维图像均能显示,而二维影像只能显示出其中80处狭窄;三维重建影像通过计算面积狭窄率比2D DSA更加准确地反映出血液动力学的改变;三维重建影像利用VA技术,比2D DSA影像在斑块显示上更具优势。结论：三维重建技术在颅内动脉狭窄的诊断中具有不可替代的作用,比2D DSA影像能提供更加丰富、准确的影像学信息。

| Abstract: | Objective To investigate the significance of three-dimensional reconstruction technique for intracranial artery stenosis diagnosis.Methods 2D DSA and three-dimensional reconstruction technique were compared from the aspects of detection rate,diameter stenosis rate,area stenosis rate and intravenous plaque.Results There was no statistical difference between 2D DSA and three-dimensional reconstruction technique,although the later was more precise.Three-dimensional reconstruction technique could show 82 stenos... |
