  • 6 min. PET acquisition
  • 120 kV
  • 45 mAs

Images and interpretation

Clinical findings

The study comparison demonstrates interval improvement in the post-therapeutic scan.

Physician impression

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.

* Results from case studies are not predictive of results in other cases. Results in other cases may vary.
