Figure 1. Representative MR Images of acute soft-tissue infection.

A, B) Mouse received PFC at day 2 post infection. Images were recorded 24 h after administration. C, D) Mouse received CLIO at day 2 post infection and was imaged 24 h after administration. A) Transverse T₂ map of PFC group mouse shows hyperintensity within infected muscle (arrow). B) ¹⁹F-SSFP CSI overlay on ¹H-TSE image of PFC treated mouse shows strong accumulation of PFC at the rim of abscess area. C) Transverse T₂ map of CLIO group mouse shows hyper-intense area diffusely circumscribed by dark spots (arrow). D) T₂* weighted image shows diffusely distributed susceptibility effects in the infected muscle (arrow). (Co: Control tube filled with PFC dilution, R: right side, L: left side of the imaged mouse).
