Abstract |
Although the exact mechanism is not clearly understood
yet, there were examples of the uptake of
radiopharmaceuticals to the soft tissue lesions with
Technetium methylene diphosphonate bone scan. Recently,
v,e experienced two cases of neuroblastoma of which
prirnary sites were imaged with" Tc-MDP bone scan
preoperatively and could rnake the diagnosis. So, we
report here that "Tc-MDP bone scan is the reasonable
method not on]y to find out the bone metastasis, but also
to diagnose the neuroblastoina preoperatively. |
