Siemens Biograph mMR
Family: Siemens Biograph · Modality: PET/MR
First commercial simultaneous PET/MR — 3T MAGNETOM magnet with integrated PET detector ring in the bore, enabling simultaneous acquisition rather than sequential. Academic research workhorse for brain, pediatric oncology, cardiac, and novel tracer studies. Displaced / complemented in new orders by the Biograph Vision Quadra PET/CT and GE Signa PET/MR on the PET/MR side.
Variant-specific considerations
- 3T MAGNETOM-class magnet + APD-based PET detector
- 60 cm patient bore (tight vs 70 cm standalone MRI)
- MR-based attenuation correction (Dixon, atlas-based)
- Installed base is predominantly academic
Parts
3T magnet, APD-based PET detector ring, MR gradient and RF chain, shared syngo.via workstation.
