Sixty-six patients with spinal metastatic disease secondary to urological malignancy underwent magnetic resonance imaging. Twenty-eight patients had clinical evidence of spinal cord compression. MRI demonstrated metastatic cord compression in 16 cases, a benign cause in two cases, nerve root involvement in five cases. In seven patients MRI demonstrated spinal metastases which were not visible on plain radiographs and isotope bone scans. Nine patients had metastatic deposits involving the cauda equina and in a further 22 patients spinal metastases were an incidental finding during MRI for staging of the primary tumour. MRI is a sensitive method of imaging spinal metastases and provides a non-invasive means of assessing patients with spinal cord compression.
66例继发于泌尿生殖系统恶性肿瘤的脊柱转移瘤患者接受了磁共振成像检查。28例患者有脊髓压迫的临床证据。磁共振成像显示16例有转移性脊髓压迫，2例为良性病因，5例有神经根受累。7例患者的磁共振成像显示有脊柱转移瘤，而在X线平片和同位素骨扫描上未见。9例患者有马尾受累的转移灶，另有22例患者在对原发肿瘤进行分期的磁共振成像检查中偶然发现脊柱转移瘤。磁共振成像是一种对脊柱转移瘤敏感的成像方法，为评估脊髓压迫患者提供了一种非侵入性手段。
