A 47-year-old woman with a left-sided multifocal infiltrating ductal carcinoma, Luminal B, referred for staging. Images were obtained in a Biograph mCT (Siemens) 60 min after i.v. injection of 363 MBq of FDG. (a) FDG-PET whole-body maximum intensity projection: multifocal left-sided breast tumour, lymph node metastasis in the left axilla, left internal mammary chain and mediastinum, left adrenal gland metastasis, multiple bilateral lung metastases, sternal, spine, and pelvic bone metastases. Physiological uptake was identified in paraspinal and supraclavicular fossa brown fat, right sternocleidomastoid muscle (arrow), myocardium (*), kidneys and bladder. (b) Axial fused FDG-PET/CT image of the multifocal tumour in the left breast (arrows), sternum (arrowhead), and right lung metastasis. (c) Axial fused FDG-PET/CT image of the left adrenal gland metastasis (arrow). (d) Axial fused FDG-PET/CT image of a vertebral metastasis (arrowhead).
