Combined 99mTc MDP bone SPECT and 99mTc sestamibi muscle SPECT for assessment of bone regrowth and free muscle flap viability in an electrical burn of scalp

A case of deep high energy electrical burn of the skull is presented. For assessment of bone regrowth and muscle flap viability after application of latissimus dorsi free flap, combined 99mTc MDP bone SPECT and 99mTc sestamibi muscle SPECT scintigraphy were used. Whereas 99mTc MDP bone SPECT showed absent uptake at the beginning, there was good uptake 3 months after flap application. 99mTc sestamibi SPECT revealed good uptake indicating normal perfusion of flap muscle tissue.
