摘　　要：目的探讨16层螺旋CT后处理技术对中老年女性脊椎骨转移的诊断价值。方法41例脊椎骨转移中老年女性患者行MSCT扫描后作图像后处理重建，得到扫描部位的MPR、MIP、SSD、VRT图像。结果后处理重建图像从不同的角度、层次显示出全部41病例的脊椎骨转移灶，而DR照片仅能显示出18病例的转移灶，其余病例DR片未能显示或只表现为骨质疏松症。MPR清楚准确显示脊椎骨转移灶及其软组织样肿瘤组织；MIP能显示脊椎整体但病灶对比显示较差；SSD及VRT多角度、立体显示脊椎骨转移病变及与周围解剖关系，VRT显示脊椎转移病灶细致结构优于SSD。结论16层螺旋CT后处理技术以MPR加VRT为最佳，它能全面、准确诊断中老年女性脊椎骨转移瘤，具有非常高的诊断和鉴别诊断价值。Objective To evaluate the value of post-imaging reconstruction of 16-slice helical CT in diagnosing spinal vertebra metastases in Middle-aged and Aged women. Methods 16-slice CT scaning and four kinds of imaging reconstructions include MPR, MIP, SSD and VRT were performed in 41 patients with spinal vertebra metastases. Results The reconstructed images showed bone metastases of vertebra in all the 41 cases ,while the lesions in 18 cases only showed with DR films, and the others showed normal or osteoporosis with DR films. MPR accurately displayed bone damage and its soft tissue mass; MIP showed the bone in whole but not clear in lesions; SSD and VRT well displayed bone metastases stereographically, VRT was better than SSD in displaying the lession of minute structure. Conclusion The synthetical application of MPR and VRT can accurately display spinal vertebra metastases in Middle-aged and Aged women , and plays an important role in the diagnosis and differential diagnosis.
