Diagram outlining the dual-time window (or coffee-break) PET-MR protocol used in Insight 46 phase 3. PET and MRI data are acquired simultaneously in early (0–30 min) and late (90–110 min post-injection) sessions. PET data are acquired in list-mode format. Example 'head-curve' plots generated with NiftyPET software are displayed, showing the total number of prompt and delayed counts detected per second across the early and late sessions. Above the plots are example images for MRI sequences acquired in each session, as well as the late session static PET image. Abbreviations: DWI, diffusion weighted imaging; FLAIR, fluid attenuated inversion recovery; MRI, magnetic resonance imaging; PET, positron emission tomography; SWI, susceptibility weighted imaging; QSM, quantitative susceptibility mapping
