[Thermography and scintigraphy of soft tissue tumors in children].

The paper is devoted to analysis of the potentialities of the combined use of thermographic and scintigraphic methods of investigation in differential diagnosis of malignant and benign soft tissue tumors in 51 children. Malignant tumors were diagnosed in 27 patients, benign tumors--in 13, pathological conditions of nontumorous etiology--in 11. Thermography revealed malignant tumors in 18 patients. The GTT based on V. S. Shapot's theory was used for the first time to increase the efficacy of thermography in differential diagnosis of malignant tumors in children. GTT sensitivity in the detection of malignant tumors was 100%. Positive scintigraphy with the tumoritropic agent 67Ga-citrate showing the highest specificity in the diagnosis of soft tissue tumors, was used in combination with thermographic methods. The combined use of the above three methods permitted differential diagnosis of malignant and benign soft tissue tumors in children with the accuracy of 90.1%.
