Evaluation of Clinical Contributions Provided by Addition of the Brain, Calvarium, and Scalp to the Limited Whole Body Imaging Area in FDG-PET/CT Tumor Imaging
Figure 1
FDG-PET/CT images of several oncological patients demonstrating findings for metastasis. (a) shows transverse unenhanced CT, PET, and PET/CT fusion images of a 64-year-old man with primary unknown tumor. Focal hypermetabolic area (black arrows) is consistent with a brain metastasis. (b) shows transverse unenhanced CT, PET, and PET/CT fusion images of a 65-year-old man with lung cancer. Peripherally hypermetabolic and centrally hypometabolic area (due to a necrotic tissue) (white arrows) is consistent with a brain metastasis. (c) shows transverse unenhanced CT, PET, and PET/CT fusion images of a 27-year-old man with non-Hodgkin lymphoma. Focal hypermetabolic area (black arrow heads) is consistent with a calvarial bone metastasis.
