Differential Diagnostics Inflammatory and Neoplastic Processes of Locomotor Sistem with <sup>199</sup>TL-сhloride Scintigraphy
Purpose was creation of the method for differential diagnostics of inflammatory and neoplastic processes of locomotor system. Patients with inflammations (n = 43) and tumors (n = 28) of locomotor system were undergone <sup>199</sup>Tl-chloride scintigraphy compared with radiology and morphology studies. The inflammations diagnosed if there were: 1) very decrease of sharpness contours of the focuses <sup>199</sup>Tl-chloride accumulation in delayed phase compared with early phase, 2) homogeneous structure of the focuses <sup>199</sup>Tl-chlo-ride accumulation, 3) RI < -0,054ER + 0,981, else tumors were diagnosed. Sensitivity, specificity and accuracy <sup>199</sup>Tl-chloride scintigraphy for the inflammations were 88,9, 85,7 and 87,3%, respectively, for the tumors were 83,3, 97,9 and 93,0%, respectively.
