Magnetic resonance imaging (MRI) is an accurate and noninvasive tool in the evaluation of children with spinal neoplasm. Localization and definition of site and extent of disease for treatment planning, the most important goals of neuroimaging in spinal neoplastic disease, have become more precise with MRI, because all spinal compartments can be seen without the need for subarachnoid puncture. Epidural and contiguous soft tissue disease, and associated vertebral abnormalities such as marrow replacement by metastatic processes, are readily confirmed during the same examination. In children, as in adults, gadolinium-diethylenetriaminepentaacetic acid aids in separating intramedullary neoplasms from associated edema or syrinx, and is essential in the evaluation of intradural-extramedullary spread of neoplasm. MRI is also useful in the exclusion of compressive lesions in children with systemic neoplasms and cord infarction or treatment-related transverse myelopathy.
磁共振成像（MRI）是评估儿童脊柱肿瘤的一种准确且无创的工具。对于脊柱肿瘤疾病，神经影像学的最重要目标是为治疗计划确定疾病的部位和范围并进行定位，而MRI使这些变得更加精确，因为无需进行蛛网膜下腔穿刺就能看到所有脊柱腔室。在同一次检查中，很容易确认硬膜外及相邻的软组织疾病以及相关的椎体异常，如转移过程导致的骨髓替代。在儿童中，与成人一样，钆喷酸葡胺有助于区分髓内肿瘤与相关的水肿或空洞，并且在评估肿瘤的硬膜内-髓外扩散方面至关重要。MRI在排除患有全身性肿瘤的儿童的压迫性病变以及脊髓梗死或治疗相关的横贯性脊髓病方面也很有用。
