摘要
目的探讨脊柱血管瘤影像学诊断价值。方法回顾性分析12例经手术及病理证实的脊柱血管瘤患者的临床及影像学检查资料，并将各种影像学检查进行了对照。结果X线片可见椎体呈典型的栅栏样改变，CT可见网眼状影像中夹杂着低密度脂肪，在MRIT1加权像上呈等或高低混杂信号，T2加权像上呈均匀高信号，并见随回波时间延长信号逐渐变亮这一典型血管瘤信号特征，MRI可发现脊髓受压变性程度。结论：脊椎血管瘤的X线、CT、MRI均有特征性表现，MRI在鉴别诊断方面优于X线、CT，MRI显示范围广，软组织分辨率高，显示椎管狭窄及脊髓的受压、变性程度，特别是对血管瘤的侵袭性的诊断明显优于CT；
purpose： To investigate the maging diagnostic value of vertebralhemangiomas .Methodos： Retrosopectively analyse the clinical and imaging data of 12 vertebral hemangiomas patients who are confirmed by operation and pathology, and compare the various kinds of Imaging check-up. Results： The eentrum of x-ray is typical change of bars,the computed tomography is the reticulation image with low density fat.It shows equal or high-low mixed signals on T（1）-weighted images,shows well-distributed high signals T（2）-weighted images.h also show a hemangiomas signal characteristic which can become brighter gradually according to the extended echo time.MRl can show the degree of spinal compression.Conclusion：Vertebral hemangiomas have special appearance in x-ray,computed tomography and MRI. MRI is better than X-ray and computed tomography in differential diagnosis.MRI can show large scope, the resolution of parenchyma is high.It＇ s better than computed tomagraphy in the appearance of spinal stenosis and the compress n the denaturation of spinal,es pecially the invasion diagnosis of the hemangiomas.io
