Impact of incorrect tissue classification in Dixon-based MR-AC: fat-water tissue inversion

BACKGROUND: The current MR-based attenuation correction (AC) used in combined PET/MR systems computes a Dixon attenuation map (MR-AC(Dixon)) based on fat and water images derived from in- and opposed-phase MRI. We observed an occasional fat/water inversion in MR-AC(Dixon). The aim of our study was t...
