From: A case of radiation-induced osteosarcoma treated effectively by boron neutron capture therapy
Fluoride-labeled boronophenylalanine-PET imaging of the brain before and after BNCT. Fluoride-labeled boronophenylalanine-PET imaging taken 1 month prior to BNCT (A and B) and 2 months after BNCT (A' and B'). A and A': axial imaging, B and B': coronal imaging. In A and B, L/N ratio was calculated as 5.0. This is theoretical proof of tumor selective destruction using BPA in BNCT. Also absorbed doses were simulated with this L/N ratio. 2 months after BNCT, A' and B' show the decreased L/N ratio as 1.2, indicating the marked effectiveness.
