Brain iron deposition after Ferumoxytol-enhanced MRI: A study of Porcine Brains.

Recent evidence of gadolinium deposition in the brain has raised safety concerns. Iron oxide nanoparticles are re-emerging as promising alternative MR contrast agents, because the iron core can be metabolized. However, long-term follow up studies of the brain after intravenous iron oxide administration have not been reported thus far.

Speeding up PET/MR for cancer staging of children and young adults.

Objective: Combining F-FDG PET with whole-body MR for paediatric cancer staging is practically feasible if imaging protocols can be streamlined. We compared F-FDG PET/STIR with accelerated F-FDG PET/FSPGR for whole-body tumour imaging in children and young adults.

Methods: Thirty-three children and young adults (17.
