Scintigraphic evaluation of sarcomata in children and adults by Ga67 citrate.

Gallium-67 scans were performed on 32 patients with adult and childhood sarcomata as part of clinical staging studies. Gallium-67 scans proved to be highly accurate in assessing sites of disease in patients with malignant schwannoma, Ewing's sarcoma, and rhabdomyosarcoma. Gallium-67 scans were inaccurate in determining sites of disease in patients with other types of sarcomata. It is concluded that Gallium-67 scanning is a useful adjunct to clinical staging in selected patients with sarcomata.
