From: Cross-sectional evaluation of FGD-avid polyostotic fibrous dysplasia: MRI, CT and PET/MRI findings
Cross-sectional imaging of left femoral bone lesions. T2-weighted, coronal MR (A), CT (B), and PET/MR (C) images showing a large lesion of the lesser trochanter and proximal diaphysis of the left femur, characterized by increased FDG metabolism corresponding to the viable portion of the tumour. Axial CT suggests cortical interruption of the posterior border of the lesser trochanter (D), corresponding to metabolically inactive tissue, as shown by PET/MRI (E). Coronal CT (F) showing two additional osteolytic lesions in the distal diaphysis and in the distal metaphysis of the left femur, respectively, with well-defined sclerotic borders and no periosteal reaction. T1-weighted PET/MRI fusion sequence (G) shows no significant FDG uptake corresponding to these additional lesions. FDG images were adjusted to the same intensity colour scale
