A 60-year-old female (BMI = 37) with a right-sided infiltrating ductal carcinoma was referred for staging. Images were obtained in a Biograph mCT (Siemens) 60 min after i.v. injection of 478 MBq of FDG. (a) FDG-PET maximum intensity projection of the thorax. (b) Axial fused FDG-PET/CT images of the primary tumour in the upper-inner quadrant (arrowhead) (SUV = 5,3), a metastasic lymph node in the right internal mammary chain (arrow) (SUVmax = 1,38) was found in the PET and histopathologically confirmed. (c) Axial fused FDG-PET/CT image of a second tumour in the same breast identified in FDG-PET (arrow) (SUVmax = 0,5), not detected by conventional imaging techniques and biopsy-proven.
