18F-FDG PET/CT imaging in a 60-year-old man with MM: (a) MIP image; (b-c) transaxial CT and fused images. In this patient, the descriptive criteria (IMPeTUs) were BM(2), F2.SP(4), L2. 18F-FDG PET/CT showed increased 18F-FDG uptake in the T4 spine (arrows). His disease stage was IA by DS Plus. The serum β2-microglobulin level was 6.08 mg/L, and the LDH level was 310 U/L. The patient was classified as III according to the RISS.
