In sixty patients with soft-tissue sarcoma, radionuclide bone scans were
92 per cent accurate in evaluating the presence or absence of involvement
of contiguous bone by the tumor itself, by the tumor's reactive
pseudocapsule, or by tissue contaminated during inadequate excision. The
scans were most helpful when the relationship of the tumor to the bone was
crucial in determining the resectability of the tumor. Meticulous imaging
technique is essential to a complete and accurate radionuclide study.
High-resolution, high-count gamma-camera scans in multiple projections are
required for precise localization of tumor.
