- FIGURE 1.
Coronal, sagittal, and transaxial CT, PET, and fused images of whole-body 18F-FDG PET/CT (A), anterior and posterior whole-body 99mTc-MIBI (B), and sagittal T1- and T1-weighted fat-saturated with gadolinium MR images of spine (C). All 3 imaging modalities, performed on the same MM patient, showed a focal + diffuse pattern of distribution. In particular, focal lesions were shown in skull, humeri, pelvis, left femur, and right fibula by whole-body 18F-FDG PET/CT; in skull, right humerus, pelvis, left femur, and right fibula by whole-body 99mTc-MIBI; and in coccygeal bone by MRI of spine and pelvis.
