[Clinical applications of bone scintigraphy in patients with benign bone diseases]

The number of bone scan cases was counted in three hospitals (general hospital = g-hosp, university hospital = un-hosp, cancer center hospital = ca-hosp). The number of bone scan cases in patients with benign bone diseases was 182 in one year in g-hosp, 235 in one year in un-hosp, 30 in one year ca-hosp. Its ratio to total bone scan cases was higher in g-hosp (51.9%) and in un-hosp (23.1%), lower in ca-hosp (3.1%). Interpretation of scintigraphic findings and comments on indication to each diseases (bone and joints diseases, rheumatic syndrome, trauma, inflammation, metabolic bone diseases and muscle disorders) were written.
