目的 :探讨MRI全脊柱移床扫描技术在脊柱转移瘤中的应用价值。方法 :对 3 7例疑有颈、胸、腰椎转移的患者 ,应用MRI全脊柱移床扫描技术 ,行各段脊柱扫描后 ,采用对接的方法完成全脊柱全程图像。结果 :3 7例均获得直观、准确地显示全部椎管内脊髓及椎体结构的连续图像。椎体单发转移瘤 9例 (颈段 2例 ,胸段 4例 ,腰段 3例 ) ;椎体多发转移瘤 2 5例 (颈、胸、腰段转移 7例 ,胸腰段转移 9例 ,颈、胸段转移 4例 ,颈、腰段转移 5例 ) ;无转移的 3例。结论 :MRI全脊柱移床扫描技术 ,可以很好显示转移瘤的部位、数目及邻近组织、结构侵犯的范围和程度 ,大大提高了定位及定性诊断的准确性。
Objective: To investigate the value of MRI whole spine bed scanning in spinal metastases. Methods: Thirty-seven patients with suspected cervical, thoracic and lumbar spine metastasis were treated with MRI full spine bed scanning technique. After spinal scanning, the whole spine image was obtained by docking. Results: All 37 cases were visually and accurately displayed continuous images of spinal canal and vertebral body in all spinal canal. Vertebra single metastases in 9 cases (2 cases of cervical, 4 cases of thoracic, lumbar 3 cases); 25 cases of multiple metastases in the vertebral body (neck, chest, lumbar transfer in 7 cases, thoracolumbar transfer in 9 cases , Neck and thoracic transfer in 4 cases, neck and lumbar metastasis in 5 cases); no metastasis in 3 cases. Conclusion: The MRI full spine bed scanning technique can well show the extent and extent of metastatic tumor sites, numbers, adjacent tissues and structures, and greatly improve the accuracy of localization and qualitative diagnosis.
