Differential diagnostic benign and malignant lesions of the spine with different regimes of bone scintigraphy

Summary. In the presented article it is examined the application of single photon emission computer tomography and single photon emission computer tomography integrated with roentgen computer tomography for differential diagnostic benign and malignant changes in the spinal structures of oncological patients. We examined 27 patients with malignant disorders. It was revealed 40 indeterminate sites of increased uptake bone-seeking radiofarmaseutical by planar bone scintigraphy in the spinal structures. Malignant or benign nature 15 from 18 sites was clinically confirmed during the single photon emission computer tomography, and 21 from 22 — during the single photon emission computer tomography and single photon emission computer tomography integrated with roentgen computer tomography . The specificity single photon emission computer tomography and single photon emission computer tomography and single photon emission computer tomography integrated with roentgen computer tomography is 83,3 and 95,5% accordingly. Thus, application single photon emission computer tomography and single photon emission computer tomography and single photon emission computer tomography integrated with roentgen computer tomography in spinal disorders essentially increases efficacy of differential diagnostics of benign and malignant sites, sensitivity and specificity bone scintigraphy for revealing metastatic spinal lesions in the oncological patients.
