This retrospective study was conducted to assess the incremental value, if any, of including the brain in whole-body fluorine-18 fluorodeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT) studies in patients with extracalvarial primary malignancies. ⋯ Inclusion of the brain routinely in whole-body F-FDG PET/CT studies detected previously unknown metastases in only 0.7% (40/5110) of studies, with negligible impact (0.15%) on staging.

This study was conducted to evaluate the role of (18)F-fluorodeoxyglucose ((18)F-FDG) PET/computed tomography (CT) in identifying missed distant metastases in patients with locally advanced breast cancer (LABC) who were assessed by conventional imaging methods. ⋯ (18)F-FDG PET/CT is a sensitive and specific imaging modality for identifying distant metastases in patients with LABC missed by conventional imaging. In addition, it detects unknown lymph nodal metastases in a significant proportion of patients and hence can be used routinely in staging of patients with LABC.
