摘　　要：目的探讨SPECT/CT断层融合显像对多发性骨髓瘤(MM)的诊断价值。资料与方法回顾性分析25例确诊为MM患者SPECT/CT骨显像的影像特征,分析融合显像对多发性骨髓瘤的诊断意义。结果 25例MM患者骨显像阳性率为88.0%(22/25),共发现病灶135个,其中放射性浓聚灶占93.3%(126/135);病灶分布以肋骨、胸椎及腰椎最常见;SPECT/CT断层融合显像23次,对83处难以明确诊断的病灶,最终79处明确了诊断,4处病灶仍难以明确诊断,同时CT新发现8处病灶。结论 SPECT/CT骨显像对多发性骨髓瘤的诊断具有较高的临床价值。Purpose To assess the diagnostic value in multiple myeloma（MM） patients with SPECT/CT fusion imaging.Materials and Methods Retrospective study was done in 25 patients diagnosed as MM.The imaging characteristics of bone SPECT/CT fusion imaging were analyzed.The clinical value of SPECT/CT in diagnosing MM was discussed.Results The positive rate of bone imaging was 88.0%（22/25） and 135 lesions were found.Among the 135 lesions,93.3%（126/135） showed higher concentration of radionuclide.The most common sites of lesions were ribs,thoracic and lumbar vertebra.SPECT/CT fusion imaging was done 23 times.Among 83 lesions which were difficult to diagnose,79 lesions were confirmed by the fusion imaging.Four lesions were still equivocal.There were 8 new lesions detected by CT tomography.Conclusion SPECT/CT fusion imaging shows better diagnostic value in MM.
