Zero-Echo Time (ZTE) has been proposed as an alternative attenuation method for PET-MR brain imaging. However, the filtering effects on these ZTE AC maps have not been explicitly discussed, in relation to effects on reconstructed and corrected images, and that is what we aim to develop in this study.
