Whole-Body PET/MR Imaging: Quantitative Evaluation of a Novel Model-Based MR Attenuation Correction Method Including Bone
Daniel Paulus,Harald H. Quick,Christian Geppert,Matthias Fenchel,Yiqiang Zhan,Gerardo Hermosillo,David Faul,Fernando E. Boada,Kent Friedman,Thomas Koesters +9 more
TL;DR: The novel MR-based AC method, combining Dixon-based soft-tissue segmentation and model-based bone estimation, improves PET quantification in whole-body hybrid PET/MR imaging, especially in bony tissue and nearby soft tissue.

Simultaneous PET/MR imaging: MR-based attenuation correction of local radiofrequency surface coils.
TL;DR: The aim of this work was to quantify the effect of local body RF coils used in the Biograph mMR hybrid PET/MR system on PET emission data and to present techniques for MR-based position determination of these specific local RF coils.

Integrated PET/MR imaging: automatic attenuation correction of flexible RF coils.
René Kartmann,Daniel Paulus,Harald Braun,Bassim Aklan,Susanne Ziegler,Bharath K. Navalpakkam,Markus G. Lentschig,Harald H. Quick +7 more
TL;DR: An algorithm is presented and evaluated which automatically determines the position of multiple RF surface coils and corrects for their attenuation of the PET emission data and accurately and reliably reduces the PET quantification errors caused by multiple partly overlapping flexibleRF surface coils.

Towards improved hardware component attenuation correction in PET/MR hybrid imaging
TL;DR: The adapted conversion from HUs to LAC at 511 keV within this study can improve hardware component AC in PET/MR hybrid imaging as shown for a flexible RF surface coil.

Radiotracer Dose Reduction in Integrated PET/MR: Implications from National Electrical Manufacturers Association Phantom Studies
Mark Oehmigen,Susanne Ziegler,Bjoern Jakoby,Jens-Christoph Georgi,Daniel Paulus,Harald H. Quick +5 more
TL;DR: An approach to reduce the injected radiotracer activity in integrated PET/ MR imaging, while maintaining PET IQ, was presented and verified under idealized experimental conditions and may serve as a basis for further clinical PET/MR studies using reduced radiot Racer dose as compared with conventional PET/CT studies.
