title: Uptake of 99mTc-phytate in osteosarcoma cases.
abstract: During routine liver spleen scintigraphic studies using 99mTc-phytate in patients with proven osteosarcoma, an unusual uptake of this radiopharamaeutical at the primary site was observed. In all, five cases have been investigated and we have observed the uptake of 99mTc-phytate at the primary tumor site. Early and delayed imaging showed persistant concentration of the radiopharmaceutical. Studies with 99mTc-sulfur colloid in one of the patients did not show any uptake at the tumor site.
