MRI of distal aspect of forelimb. Top row: scan site on a sagittal image. Second and third rows: control limb. Fourth and fifth rows: treated limb. Second and fourth rows: short TE scan. Third and fifth rows: long TE scan. Left columns: images obtained proximal to proximal sesamoid bones. Middle columns: images obtained just distal to proximal sesamoid bones. Right columns: images obtained along distal aspect of proximal phalanx. Susceptibility artefacts (confirmed as such due to larger size on long TE images, compatible with presence of MION particles) identified at multiple sites in treated limb, but not in control limb. Proximally, susceptibility artefact outside tendon sheath (large black arrows) in region of injection site. Just distal to proximal sesamoid bones, susceptibility artefact identified at several sites in lateral tendon sheath (solid narrow white arrows). Distally, susceptibility artefact identified in lateral (solid narrow black arrow) and medial tendon sheath (dashed narrow black arrow). TE echo time
