Synopsis

Keywords: PET/MR, PET/MRSimultaneous positron emission tomography/magnetic resonance imaging (PET/MRI) shows advantages in clinical and research applications for human brain. In this work, MRI compatibility of a brain PET insert integrated with a quadrature birdcage transmit /47-channel receiver head coil assembly was studied. The results of RF field (B₁⁺) distribution, signal-to-noise ratio (SNR) and static field inhomogeneity (ΔB₀) show MRI compatibility of the brain PET insert. Simultaneous PET/MRI was implemented, which demonstrated a high performance of the brain PET/MRI system.
