            Female, 61 year old, diagnosed with right breast cancer (moderately differentiated invasive ductal carcinoma, with involvement of skin). PET-FDG with 12 mCi, injected with blood glucose level of 96 mg/dl showed in multiple focus of intense increased right breast  tracer uptake anteriorly, associated with a posterior horizontal mass with irregular borders  which measures 7 x 3.5 cm, maximun SUV uptake of 12 (black arrows). In addition, there are at least 4 areas of  radiopharmaceutical uptake in right axillary region, the largest 9 mm and maximun SUV of 5.8, and another focus  ipsilateral supraclavicular of 1.5 cm maximun SUV of 5.8 (red arrows).
 

            In 11 patients,  Azuma et al., found that tumor cell density of intraductal carcinoma appears strongly correlated to detection by FDG-PET/CT (1).

             Adler at al conclude that FDG-based lesion with dedicated positron emission mammography localization information may be combined with the lesion X-ray attenuation characteristics using this common imaging platform (2).
