64排螺旋CT在骨关节外伤诊断中的应用

Application of 64 slice spiral CT in diagnosis of bone and joint trauma

目的探讨并分析64排螺旋CT在骨关节外伤诊断中的应用情况。方法选取我院2014年3月~2015年2月收治的骨关节外伤患者共134例,对这134例患者进行64排螺旋CT检查,并使用三维表面重建进行图像处理,与X平片相比较。结果 X平片、轴位图像、平面重建（MPR）、容积再现（VR）和表面遮盖法（SSD）关于各类骨关节外伤的总检出率分别为74.63%、95.52%、100%、88.06%、79.10%,其中MPR检出率高于其他检查方法（P〈0.05）,X线平片检出率最低;X平片与MPR、CT轴位图像、VR、SSD相比较,其漏诊率及误诊率均高于MPR、CT轴位图像、VR、SSD（P〈0.05）64排螺旋CT能够清楚显示出骨关节内部细节的情况、内部骨折线、骨碎片等。结论 64排螺旋CT检查具有良好的诊断效果,能及时掌控骨关节外伤的形态变化,提高图像质量,有利于临床治疗,值得进行推广使用。

Objective To investigate and analyze the application of 64 slice spiral CT in diagnosis of bone and joint trauma. Methods 134 cases of patients with trauma of bones and joints were selected in our hospital from March, 2014 to February, 2015. They were used by 64 slice spiral CT examination, and the use of 3D surface reconstruction for image processing, and X-ray plain film. Results The flat, axial images and multiplanar reconstruction（MPR）, volume rendering（VR） and surface cover（SSD） on all kinds of trauma of bone and joint total detection rate was 74.63% and 95.52%, 100% and 88.06%, 79.10% respectively, including MPR detection rate is higher than that of other examination methods（P〈0.05）, X-ray detection rate is the lowest; 64 slice spiral CT can clearly show the internal details of bones and joints, internal fracture line, bone fragments. Conclusion The 64 slice spiral CT has good diagnostic effect, can control the morphological changes of bone joint trauma, improve the quality of the image, and can help clinical treatment.
