The results of radionuclide visualization of 147 patients with primary bone pathology were analyzed using probability algorithms. This analysis resulted in the determination of several groups of signs of various degrees of reliability in the diagnosis of some types of bone pathology. Diagnostic algorithms allow summing up and classifying practical experience and to test hypotheses, put forward by some of the physicians as a result of their practical activities. The use of probability algorithms in radionuclide studies is necessitated by a great variety of radiopharmaceuticals and a multitude of radiodiagnostic approaches to the standardization of methods and unification of diagnostic decisions.

The optimum value of diagnostic procedure in the assessment of RP tumoritrophism (99mTc-pyrophosphate) was shown. The results of radionuclide studies using 99mTc-pyrophosphate in 193 patients with bone pathology were cited by way of example. Diagnostic thresholds with error levels were established. The diagnostic criteria (sensitivity, specificity, accuracy, etc.) were established proceeding from the criteria of malignant and benign features. Some differential-diagnostic potentialities of 99mTc-pyrophosphate in the recognition of certain groups of bone pathology were revealed.
