One challenge of PET/MR imaging is the correction of photon attenuation caused by hardware in the field-of-view. For the particular case of MR local coil attenuation, a solution based on stored templates is provided by commercially available clinical PET/MR systems. This solution, however, is limited to rigid coils docked in a pre-defined position. A more general method encompassing other coil types would be desirable to improve the accuracy of PET images. The goal of the present study is to investigate the accuracy of fast ZTE acquisitions for the correction of local coil attenuation.
