Fig. 2From: Comparison of the image-derived radioactivity and blood-sample radioactivity for estimating the clinical indicators of the efficacy of boron neutron capture therapy (BNCT): 4-borono-2-18F-fluoro-phenylalanine (FBPA) PET studyTime-course of the PET image-derived blood radioactivity. Representative decay-corrected axial images of the left ventricle in a 56-year-old healthy woman after injection of FBPA. High accumulation in the left ventricle was observed soon after the FBPA injection, to promptly decrease soon thereafter and gradually approach a constant level at 20 min later after the tracer injectionBack to article page
