This 60 year-old, 157 lb / 71.6 kg male patient has a history of locoregional head and neck cancer. PET/CT was performed prior to treatment and again following therapy.
- 6 min. PET acquisition
- 120 kV
- 45 mAs
The study comparison demonstrates interval improvement in the post-therapeutic scan.
PET/CT improves the accuracy in evaluating therapy response over CT alone. In patients where PET/CT reveals no residual lymphadenopathy, evidence has shown that planned neck dissection may no longer be necessary.
