目的比较X线平片、CT、MRI对骶骨肿瘤的诊断价值。方法回顾分析了25例骶骨肿瘤的各种影像学表现。结果平片能显示较明显的病变,有良好的空间分辨率;CT能显示较早期的病变,并清楚显示病变的结构与邻近组织关系;MRI可以及时发现病变,并能反映病变的组织成分,以及骨质和软组织受累的范围。结论对骶骨肿瘤的诊断,X线平片、CT和MRI各有特点。三者应互相结合,取长补短。
Objective To compare the diagnostic value of X-ray, CT and MRI in sacral tumors. Methods The imaging features of 25 sacral tumors were retrospectively analyzed. Results plain film can show more obvious lesions, with good spatial resolution; CT can show earlier lesions, and clearly shows the relationship between the structure of the lesion and adjacent tissues; MRI can detect lesions, and can reflect the composition of the lesion, As well as the range of bone and soft tissue involvement. Conclusion The diagnosis of sacral tumors, X-ray, CT and MRI have their own characteristics. The three should be combined with each other, learn from each other.
