脊柱转移瘤影像学研究进展

Imaging of spinal metastases

骨骼是转移性疾病的第三大好发部位,仅次于肺和肝。脊柱又是骨转移最常见的部位,最常见于胸椎,其次是腰椎和颈椎。5%-10%的癌症患者会发展为脊柱转移。不同的原发肿瘤的脊柱转移瘤发生率也不尽相同。常见的易发生骨转移的肿瘤包括：乳腺癌（72%）、

The spine is the third most common site for metastatic diseases, following the lung and the liver. Metastases to the spine can involve the bone, epidural space, leptomeninges, and spinal cord. Imaging modalities play complimentary roles in the evaluation of spinal metastatic disease. Imaging examination is the direct evidence to determine the bone metastases, the early detection of bone metastasis and complications caused by bone metastases, tumor invasion, biopsy positioning, etc. It is of great significance. CT can clearly delineate the osseous integrity, while MRI can display the soft tissue involvement. Physiologic properties can be evaluated with other imaging modalities such like FDG-PET and advanced MRI. Imaging plays a fundamental role in not only the diagnosis but also treatment planning of spinal metastatic disease.
