(a) Representative axial and coronal PET/MR fusion images and corresponding T1-weighted MR images of control (left), [89Zr]Zr-IL-23p19–injected (center), and [18F]FSPG–injected (right) mice. SUVmean of [89Zr]Zr-IL-23p19 (b) and [18F]FSPG (c). Lesion-to-muscle uptake ratio of [89Zr]Zr-IL-23p19 (d) and [18F]FSPG (e). Data are presented as mean ± SD (n = 6 per group).
