3. The 18FDG-PET scan shows increased tracer activity within the left upper lobe nodule only
The 18FDG-PET scan shows increased tracer activity only within the left upper lobe; the other small nodules seen at thoracic CT show no tracer utilization. Note that these other nodules are quite small, and the lack of tracer utilization in such small nodules should not be taken as evidence that they are benign or non-aggressive in nature; rather, the nodules may simply be below the limit of 18FDG-PET scan resolution. No evidence of tracer utilization within mediastinal or peribronchial lymph nodes is noted on the images provided. The 18FDG-PET scan appears technically adequate- there is clear activity within blood pool, indicating that tracer has been properly administered and distributed.).
