Imaging performance of 18F-FDG PET-CT on patients with multiple myeloma / 实用肿瘤学杂志

ABSTRACT

Objective The objective of this study was to investigate the imaging findings of 18 F-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.
