The purpose of this paper is to discuss the capabilities and drawbacks of MR imaging in patients with trauma to the spine and degenerative spinal conditions. In spinal trauma MR imaging is secondary to plain X-ray films and CT because of the greater availability and ease of performance of these techniques and their superior capability for detecting vertebral fractures. Magnetic resonance imaging is useful for detecting ligamentous ruptures and intraspinal mass lesions such as hematoma, and for assessing the state of the spinal cord and prognosis of a cord injury. In degenerative spinal disease the necessity is emphasized of critically evaluating the clinical relevance of any abnormal feature detected, as findings of degenerative pathology are common in individuals without symptoms. Magnetic resonance myelography permits rapid and accurate assessment of the state of the lumbar nerve roots (compressed or not). In the cervical region the quality of the myelographic picture is often degraded in patients with a narrow spinal canal.
本文旨在探讨磁共振成像（MR）在脊柱创伤患者和脊柱退行性疾病中的应用能力及不足之处。在脊柱创伤中，由于普通X线片和CT更易获取且操作简便，以及它们在检测椎体骨折方面具有更高的能力，因此MR成像排在它们之后。磁共振成像对于检测韧带断裂和脊髓内肿块病变（如血肿）以及评估脊髓状态和脊髓损伤的预后很有用。在脊柱退行性疾病中，强调了严格评估所检测到的任何异常特征的临床相关性的必要性，因为在无症状个体中退行性病理表现很常见。磁共振脊髓造影可以快速、准确地评估腰神经根的状态（是否受压）。在颈椎区域，脊髓造影图像的质量在椎管狭窄的患者中常常会下降。
