Synopsis

¹⁸F-fluoro-Boronophenylalanine (FBPA) Positron emission tomography (PET) plays a crucial role for patient selection prior to boron neutron capture therapy. As integrated PET-MR is being used frequently in clinical research and routine, this study aimed to compare regional difference of brain standard uptake values on the PET quantification accuracy in FBPA PET-CT and PET-MR among lesions and normal tissues. Compared to SUVR in PET-CT, PET-MR data showed significant lower SUVR in lesion regions, while no significance was observed in the normal tissue regions. The result of this study may accelerate the routine use of PET-MR in tumoral quantification before BNCT.
