【摘要】 目的 :评价 3DCT曲线重建显示椎动脉能力和准确性。方法 :对 10具颈椎标本的 16根椎动脉行 DSA和 3DCT曲线重建对照研究。在 C5 或 C6 的横突孔处、椎动脉的内侧置入小骨片 ,形成实验性椎动脉狭窄。结果 :3DCT曲线重建图像显示椎动脉的形态学改变 (如变细、狭窄、扭曲等 )的能力与 DSA相近。椎动脉实验性狭窄研究发现 3DCT曲线重建能揭示骨赘和椎动脉的关系。重建图像清晰。结论 :3DCT曲线重建是一种准确可靠、无创伤性诊断椎动脉型颈椎病的影像学方法更多还原

【Abstract】 Objective:To evaluate the capability and accurancy of demonstrating vertebral artery (VA) with 3D CT curved reconstruction.Methods:16 VAs of 10 cadavers were studied with 3D CT curved reconstruction and DSA.Experimental VA narrowings were made by inserting bony fragments into the medial sides of VAs at the foramen transversium of C 5 or C 6.Results:3D CT curved reconstruction had the same capability as DSA in showing the morphological changes of VA,such as narrowing and curving.The relationship between cervical spondylosis and VAs could be found by means of the experimental study of VA′s narrowing.The images of 3D CT curved reconstruction were good.Conclusion:3 DCT curved reconstruction is an accurate and noninvasive modality in diagnosing cervical spondylosis with vertebral insufficency.更多还原
