NF2 and neoplasm: In another PET study, Anton-Rodriguez et al. [3] evaluated uptake of the metabolic PET tracer 18F-FDG and the cellular proliferation marker 18F-FLT (3’-deoxy- 3’-fluorothymidine) in six patients with NF2-SWN associated VS, demonstrating significantly higher uptake in rapidly growing VSs compared to indolent or slow growing tumours.
