Simultaneous MRI and PET imaging for clinical application has recently become feasible. While significant work has been done to limit hardware interference, less has been done to explore potential physiologic interference. This study explores the impact of MR acoustic noise on FDP-PET uptake in the human auditory cortex. Healthy volunteers were injected with 5 mCi of FDG and dynamic PET imaging was performed for 40 minutes using the BrainPET in the presence and absence of simultaneously acquired MR. Static 40 to 60 minute frames were also examined. No significant change was noted in either the PET data or the PET detector performance.
