69-year-old patient with invasive ductal carcinoma (IDC) G2 with primary breast cancer prior to treatment. Coronal CT reconstruction shows contrast enhancement in a lesion with a diameter of 2.2 cm in the right breast (a). The tumor is visually detectable on 68Ga-Pentixafor PET with a corresponding SUVmax of 3.2 (b). On 18F-FDG PET/CT, the lesion demonstrates a significantly higher tracer uptake (SUVmax of 16.5) (c)
