MSCT及后处理技术对强直性脊柱炎的诊断价值

摘要

Objective:To review the image feature of ankylosing spondylitis,and discuss the diagnostic value of MSCT and image processing technology on ankylosing spondylitis.Method:Collected 8 paitents’image date with clinical confirmed AS from 2005-2012 year,and analysised the image feature of MSCT retrospective.All patients were scaned with piain CT,and reconstructed the thin image,and then to do the image processing,which main technology we choosed was MPR and VR.Result:Fuzzy、erosion and hardening changes on sacroiliac jiont appeared in all 8 cases,deformed sample change on the lumbar appeared in 6 cases,which with the deformed sample change on the thoracic appeared in 1 case,obvious erosion,hardening and cystic changes on small joint appeared in all 8 cases so.Conclusion:Subtle change on bones,joints and ligaments of AS cases can be clear revealed by MSCT and image processing technolog,which can be applied as an important approach for the AS.%　　目的：复习强直性脊柱炎的影像特征，并探讨MSCT及后处理技术对强直性脊柱炎的诊断价值。方法：收集2005-2012年8例经临床证实的AS病例资料，回顾性分析其MSCT表现，所有患者均仅行CT平扫，并在工作站上薄层重建图像及对图像进行后处理，后处理技术主要选择MPR、VR。结果：8例AS均有骶髂关节模糊、侵蚀、硬化，6例腰椎出现“竹节”样改变，1例胸椎表现为“竹节”样改变，8例腰椎小关节均出现明显侵蚀、硬化和囊变。结论：MSCT及后处理技术能清晰显示AS骨关节和韧带的细微改变，可作为诊断AS的重要手段。
