MR-based Attenuation Correction (MRAC) is crucial for
PET quantitation and image quality in a hybrid PET/MR
system. An ideal MR sequence for attenuation correction
should at least satisfy three criteria: (1) whole-body
scan capabilities; (2) good anatomical localization; (3)
robust tissue classification. UTE-mDixon (if it is still
meant generally here, it should be Dixon, not mDixon,
and you should add some references) sequences have
demonstrated great potential for enhancing contrast of
cortical bone and for water/fat separation within a
single acquisition. Herein we report our initial
experience of utilizing a UTE-mDixon sequence for
whole-body PET/MR attenuation correction
