Fig. 1. Plantar scintigraphic projection of the hock region with focal increased uptake of the right hind proximal metatar- sus. Transverse T1 image of the proximal metatarsus of the right hind limb in the same region as the scintigraphic uptake showing only suspensory ligament pathology.
Fig. 2. MRI images of the region of increased uptake on the scintigraphy examination. A, Proton density axial, B, T2 short tau inversion recovery (STIR) axial, C, T1 VIBE FS axial, D, proton density FS axial, E, T2 STIR sagittal, and F, T2 STIR dorsal. Note the increased signal (white area in the palmar aspect of MC3) on images B–F and decreased signal on A. This is consistent with bone “edema.” Note the normal appearance to the suspensory ligament, which contains fat and muscle, creating a region of light gray and white within the black ligament fibers.
