pyrophosphate and Spinal-Cord-Neoplasms

The paper is concerned with the results of radionuclide investigation of 51 patients with different tumors located beyond the osseous tissue. In spite of the fact that 99mTc-phosphates were well known as agents for radionuclide diagnosis of bone tumors, they can be employed for obtaining certain diagnostic information concerning topical diagnosis and the determination of a degree of the distribution of processes of nonskeletogenous nature. Of 51 patients with soft tissue pathology clear visualization of lesion foci was obtained in 34 patients (66.7%). Positive results of radionuclide diagnosis with 99mTc-pyrophosphate were noted in scintigraphy of patients with breast, ovarian, soft tissue and maxillofacial tumors. Besides, clear visualization of lesion foci was achieved in 6 of 11 patients with benign diseases: postoperative scars, inflammatory infiltrates, synovioma. The results obtained indicated the absence of necessary specificity of 99mTc-phosphates to osseous tissue.
