Description
PET/MR presents a unique opportunity to acquire simultaneous, complementary, functional imaging data in human and animal studies. Specifically, 23Na and 13C, termed 'x-nuclei', present novel imaging contrasts which inform upon cellular function. Due to the differing magnetic properties of x-nuclei, increased demands are placed upon gradient and RF hardware for acquisition. However, little data has been shown assessing the performance of PET detectors during x-nuclei MR imaging acquisitions. This study demonstrates negligible effect of a 3D 23Na-MRI sequence on the PET detection performance and count rate. We believe these results will help inform future studies integrating 23Na-MRI in simultaneous PET/MR acquisitions.
