Positron emission tomography–magnetic resonance imaging (PET/MRI, PET–MRI, or PET/MR) is a hybrid imaging technology that incorporates magnetic resonance imaging (MRI) soft tissue morphological imaging and positron emission tomography (PET) functional imaging.

The combination of PET and MRI was mentioned in a 1991 Phd thesis by R. Raylman. Simultaneous PET/MR detection was first demonstrated in 1997, however it took another 13 years, and new detector technologies, for clinical systems to become commercially available.
