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
OBJECTIVE: To evaluate the ability and accuracy of vertebral artery reconstruction using 3DCT curve reconstruction. Methods: DSA and 3DCT curve reconstruction of 16 vertebral arteries in 10 cervical specimens were performed. In the C5 or C6 transverse foramen, the inside of the vertebral artery into the small bone slices, the formation of experimental vertebral artery stenosis. Results: 3DCT curve reconstruction showed similar morphologic changes (such as narrowing, stenosis, distortion, etc.) of vertebral artery and DSA. Vertebral artery stenosis study found that 3DCT curve reconstruction can reveal the relationship between osteophytes and vertebral artery. Reconstruction of the image clear. Conclusion: 3DCT curve reconstruction is an accurate and reliable imaging method for non-invasive diagnosis of cervical spondylosis of vertebral artery
