title: Unexpected detection of brain metastases by 18F-NaF PET/CT in a patient with lung cancer.
abstract: In recent years, the inconsistent supply of (99m)Tc and the increasingly widespread use of PET/CT have led to a renewed interest in PET/CT bone scans using (18)F-NaF. Recently, a 64-year-old man with biopsy-proven lung cancer underwent an (18)F-NaF PET/CT bone scan due to a shortage of (99m)Tc. Unexpectedly, multiple nodular foci of increased tracer uptake were present in the brain, whereas there were no definitive bone metastases detected. Subsequently, brain MRI confirmed the presence of brain metastases.
