Spinal disease can be divided into intramedullary, extramedullary-intradural, and extradural compartments. In the cord (intramedullary compartment), gadolinium chelates are useful to diagnose primary and metastatic tumors, inflammation, and demyelination, and to evaluate syringomyelia when a Chiari I malformation is not present. In the extramedullary-intradural compartment, gadolinium chelates are useful for the diagnosis of drop metastases, meningiomas, and schwannomas. In the extradural compartment, gadolinium chelates are most useful to distinguish recurrent disc herniation from epidural fibrosis in the postoperative back and may be useful to diagnosis the soft tissue component of osseous metastases.
脊柱疾病可分为髓内、髓外硬膜内和硬膜外腔隙。在脊髓（髓内腔隙），钆螯合物有助于诊断原发性和转移性肿瘤、炎症及脱髓鞘疾病，并且在不存在Chiari I畸形时评估脊髓空洞症。在髓外硬膜内腔隙，钆螯合物有助于诊断转移性肿瘤、脑膜瘤和神经鞘瘤。在硬膜外腔隙，钆螯合物对于区分术后背部复发性椎间盘突出与硬膜外纤维化最为有用，并且可能有助于诊断骨转移的软组织成分。
