摘要: 目的 探讨18F-FDG PET-CT显像在多发性骨髓瘤(Multiple myeloma,MM)中的影像表现。方法选取我院2014年1月—2016年10月收治的经病理确诊为MM的患者15例,对这15例患者的临床资料进行回顾性统计分析,获得18F-FDG PET-CT显像诊断MM的SUVmax值范围,并总结分析15例患者的影像表现。结果 15例MM患者18F-FDG PET-CT显像显示总病灶数202处,其中PET显示病灶数176处,CT显示病灶数171处。18F-FDG PET-CT显像诊断MM的SUVmax范围为1.41~16.28。15例MM患者中14例出现不同程度骨质破坏,1例骨质密度稍增高伴FDG代谢活性轻度增高。骨质破坏多表现为穿凿样、溶骨性、膨胀性及片状骨质破坏,成骨性病变较少见。结论 18F-FDG PET-CT显像可结合功能代谢及解剖信息清楚地显示MM的影像学特征,为临床诊断提供更多线索,有助于提高MM的诊断准确率。

Abstract: Objective The objective of this study was to investigate the imaging findings of 18F-FDG PET-CT in patients with multiple myeloma(MM).Methods Fifteen patients with multiple myeloma were enrolled in our hospital from January 2014 to October 2016.The clinical data of these patients were retrospectively analyzed to obtain the range of SUVmax values by 18F-FDG PET-CT imaging performance.Results Fifteen MM patients with 18F-FDG PET-CT showed a total number of lesions 202,the number of lesions 176 in PET and the number of lesions 171 in CT.The SUVmax range of 18F-FDG PET-CT imaging in the diagnosis of MM was 1.41~16.28.Fourteen cases of 15 MM patients were found varying degrees of bone destruction;one case showed a slightly increased bone density and also slightly increased FDG metabolic activity.Bone destruction was more performance for the chisel-like,osteolytic,swelling and flaky bone destruction.The osteogenesis lesions were rare.Conclusion 18F-FDG PET-CT imaging can clearly show the imaging features of MM by combining functional metabolic and anatomical information,and provide more clues for clinical diagnosis,which can improve the diagnostic accuracy of MM.
