Research Abstract |
The purpose of this study was to establish a method for evaluating quantitatively BF-227 amyloid PET. Spatial normalization using BF-227 template showed equal to or higher precision than spatial normalization using MRI template. The new method proposed in this study to determine cerebellar reference region is useful for making SUVR (standard uptake value ratio) image for BF-227 PET. Partial volume correction with resolution recovery did not discriminate the accumulation between the cortex and white matter. Further improvement of algorithm is necessary. The methods proved to be useful for BF-227 PET can be applied to other amyloid imaging tracers.
