摘　　要：目的:探讨眶尖区的多层螺旋CT(MSCT)解剖,为该区疾病的影像诊断提供可靠依据。方法:采用MSCT及三维显示技术观察10例(20侧)正常志愿者眶尖区。结果:MSCT及三维显示技术对眶尖区骨性结构显示良好。以Reid基线为准,80%的视神经眶内段和管内段可在同一层面上全程显示。结论:MSCT及三维显示技术是活体研究眶尖区形态大小的最佳方法之一。外伤性骨折时应以CT检查为首选。Objective: To provide reliable basis for clinical diagnosis by studying multislice spiral CT (MSCT) anatomy of the optic apex region.Methods:MSCT scanning and three dimensional images of the optic apex region were observed in 10 normal adult volunteers.Results:The osseous structures of optic apex were well demonstrated using MSCT and three dimensional rendering techniques. Eighty percent of the intraorbital and intracanalicular segments of optic nerve could be shown in the same transverse plane when Reid’s base line was used as baseline.Conclusion:MSCT and three dimensional rendering techniques is one of the best methods to study the morphology of orbital apex region in vivo. CT is the first choice for the diagnosis of traumatic facture.
