Figure 2.
Figure 2. A 71-year-old male underwent left under-knee amputation 6 months ago, referred with a draining wound for bone scintigraphy. Scintigraphy was reported as osteomyelitis: (a) perfusion images; (b) blood pool images; (c) 3 h late anterior knee static images; (d) 24 h late knee static anterior images.
Figure 3.
Figure 3. A 44-year-old female underwent second and third right toe amputation due to diabetes 1 year ago. One month after the amputation, bone scintigraphy was taken for the draining wound. After the antibiotic therapy, symptoms decreased. After recurrence of the draining wound in the stump region, bone scintigraphy was performed again. In the comparative evaluation, the images were reported as chronic osteomyelitis: (a) perfusion images; (b) blood pool images; (c) 3 h static images; (d) 3 h lateral static images.
