| Outline of Final Research Achievements |
Through a five-year investigation, a protocol for high-speed imaging using whole-body PET/MRI has been established. This study successfully determined the imaging method for whole-body NaF PET/MRI in patients with castration-resistant prostate cancer and bone metastases, which is the focus of this research project. PET phantom tests were conducted on a PET/MRI device to examine fundamental image reconstruction. Multiple image reconstruction approaches under clinical conditions were explored to validate the optimal parameter (β-value) for the Bayesian Penalized Likelihood (BPL) method used for high-speed PET imaging. It was demonstrated that the previously determined optimal β-value remains optimal in the phantom tests. The findings were presented at the 2022 American Society of Nuclear Medicine and published in the journal "Diagnostics."
