摘要
目的比较放射性核素骨显像(简称骨显像)与脊柱MR检查对鼻咽癌脊柱转移瘤的检出能力。方法回顾性分析47例鼻咽癌伴有脊柱转移患者的骨显像和脊柱MR检查结果,以累及椎体个数为单位,比较两种检查方法对脊柱转移瘤的检出能力。结果随访证实47例患者共187个椎体有转移灶。骨显像检出153个(153/187,81.82%),脊柱MR检出182个椎体(182/187,97.33%),二者差异有统计学意义(χ2=23.758,P=0.000)。结论脊柱MR比骨显像更能有效地检出鼻咽癌的脊柱骨转移灶,可作为早期诊断脊柱骨转移的首选方法。
Objective To compare the diagnostic efficacy of bone scintigraphy and MRI on vertebral metastases in patients with nasopharyngeal cancer（NPC）.Methods Forty-seven patients of NPC and clinically confirmed metastatic disease in spine underwent bone scintigraphy and MR examination.The number of involved vertebri diagnosed with two methods were calculated and compared retrospectively.Results A total of 187 vertebral metastases were found in 47 patients,among which 153（81.82%） were detected with bone scintigarphy and 182（97.33%） were diagnosed with MRI（χ2=23.758,P=0.000）.Conclusion Compared with bone scintigraphy,MRI is superior in detecting vertebral metastases from NPC,and can be used as the first choice for the early diagnosis of spinal metastases from NPC.
