椎体血管瘤的比较影像学研究

目的：探讨X线平片、CT、MRI三种影像学检查方法对诊断椎体血管瘤的应用价值。方法：搜集13个椎体血管瘤病灶的X线平片、CT及MRI表现，对其影像特征进行对比研究。结果：X线检查显示10个病灶，骨小梁呈“栅栏状”改变；CT扫描显示12个病灶，横断面表现为蜂窝状或风状结构；MRI扫描显示全部13个病灶，10例显示为短T1、长T2的信号影，3例显示为长T1、长T2的信号影，并且清晰显示了脊髓情况。结论：椎体血管瘤在X线平片、CT及MRI上均有特征性影像学表现，CT、MRI对椎体血管瘤的检出率高于X线平片。MRI对椎体血管瘤的诊断、分型及指导治疗均具有十分重要的意义。

The comparative radiology of vertebral hemangiomas

Objective: To evaluate X - ray, CT and MRI in the diagnosis of Vertebral hemangiomas (VHs). Materials and Meth- ods: Thirteen VHs with X - ray, CT and MRI examinations were retrospectively analyzed to study the imaging characteristics. Result: Ten lesions of VHs with typical vertical orientation of accentuated trabeculae in the vertebral bodies were presented on X - ray film. Twelve lesions appeared as honeycomb - like or mesh - like features in cross section on CT. MRI scanning discovered all 13 le- lesions and the changes of spinal cord. Ten lesions appeared high signal on both T1 - and T2 - weighted image. Three lesions appeared low signal on T1 - weighted image and high signal on T2 - weighted image. Conclusion: All imaging examination, including X - ray, CT and MRI, have characteristic features. MRI and CT are more sensitive than coventional X - ray. MRI plays an important role in diagno- sis, classcification and therapeutic planning of VHs.
