膝部病变CT和X线的对照分析

To Analyze the Imaging Feature of CT and X-Ray in the Joint Diseases

目的 :分析CT和X线在膝部病变中的诊断价值。材料与方法 :收集膝部病变 2 1例 ,全部经X线和CT检查 ,其中骨折由影像学确诊 ,其他病变由关节镜和手术病理证实。分析两种检查方法的优缺点。结果 :9例为胫骨平台骨折 ,其中1例合并髁间嵴撕脱。 1例为单纯髁间嵴撕脱。CT全部确诊 ,而X线发现 8例。 6例半月板损伤 ,CT扫描发现 3例而X线为阴性。CT确诊 3例月国窝囊肿和 2例绒毛结节性滑膜炎 ,而X线无特异性发现。结论 :尽管普通X线对骨折诊断准确率很高 ,但相比CT而言 ,后者可以具体定位和定型 ,对指导外科治疗很有帮助。对半月板损伤 ,常规CT和X线 ,尤其是后者 ,存在很大局限性。对月国窝囊肿和绒毛结节性滑膜炎 ,CT诊断价值远远高于X线。

Purpose:To study the value of CT and X-ray in the joint discases.Materials and Methods:X-ray and CT were conducted in 21 cases.Advantages and disadvantages of two checking methods were discussed.Results:Of all cases,9 cases were tibia plateau fractures,one of them combined with intercondylar eminence fracture,1 case was only intercondylar eminence fracture.CT scan found all of them and X-ray found 8 cases.CT scan found 3 cases and X-ray had no specific discovery in 6 cases of meniscus injuries.CT displayed the shape and size of fossa poplitea cyst in 3 cases and villonodular synovitis in 2 cases,while X-ray had no specific findings.Conclusion:Although the accuracy of X-ray,It only displays fractrue existing or not.CT is valuable for surgical treatment according to the location and type of fracture.Both CT and X-ray,especially the latter,have local value to meniscus injuries.The value of CT is more useful than that of X-ray to fossa poplitea cyst and villonodular synovitis.
