Interventions and Outcome Measures

Arms

experimental: Whole Body DWI plus FDG PET/MRI

Participants will receive 5 to 10 Megabecquerel (MBq) +/- 10% of 18F-fluorodeoxyglucose as an intravenous injection and undergo a FDG PET/MRI scan that will extend from the vertex to the mid-thighs. Imaging will be performed from vertex to mid-thighs using standard protocol. Participants may also obtain an optional second FDG PET/MRI with DWI within 6 months.

Interventions

Fluorodeoxyglucose F18

Given IV as part of routine imaging

Positron Emission Tomography combined with Magnetic resonance imaging (PET/MRI)

Imaging procedure

Whole Body Magnetic Resonance Imaging with Diffusion-Weighted Imaging (WB-MRI-DWI)

Imaging procedure done concurrently with PET/MRI

General Electric (GE) SIGNA PET/MR

Imaging device

Primary outcome measure

  • Proportion of lesions characterized as positive [ Time Frame: Up to 6 months ]
