The maximum intensity projection (MIP) image of an 18 F-FDG PET/CT scan in a patient with invasive ductal carcinoma of the breast and an elevated HF value. The image shows increased 18F-FDG uptake in the right breast (black arrow) and ipsilateral axillary lymph nodes (white arrow). The SUVmax of the right breast mass was 9.0, the MTV was 49.79 cm3, the TLG was 276.45, and the heterogeneity factor (HF) was 2.12. This patient died from disease progression 17 months after acquisition of this image.
