Twelve patients with tumors involving the osseous spine were evaluated with magnetic resonance (MR) imaging and computed tomography (CT), six with and six without intrathecal injection of contrast material. MR imaging was found to be superior to CT without contrast material and equal to CT with contrast material in delineating the anatomic relationships of the tumors, including bone involvement, spinal canal invasion, paraspinal soft-tissue extension, and vascular involvement. Since MR imaging can provide most of the anatomic information necessary for treatment planning, intrathecal injection of contrast material can be avoided in most instances when evaluating tumor involvement of the osseous spine. However, CT without contrast medium was superior to MR imaging in showing critical cortical bone destruction and calcified tumor matrix.
对12例累及骨性脊柱的肿瘤患者进行了磁共振（MR）成像和计算机断层扫描（CT）评估，其中6例进行了鞘内注射对比剂，6例未进行。结果发现，在描绘肿瘤的解剖关系方面，包括骨受累、椎管侵犯、椎旁软组织延伸和血管受累，MR成像优于未注射对比剂的CT，与注射对比剂的CT相当。由于MR成像能够提供治疗计划所需的大部分解剖信息，因此在评估骨性脊柱肿瘤受累时，大多数情况下可以避免鞘内注射对比剂。然而，未注射对比剂的CT在显示关键的皮质骨破坏和钙化的肿瘤基质方面优于MR成像。
