[Diagnostic value of thermography and Tc 99m bleomycin scintigraphy for nodules of the thyroid (author's transl)].
The combined interest of thermography and 99mTc Bleomycin scintigraphy in the differential diagnosis of a cold thyroid nodule was evaluated in 86 patients. In all cases a histological examination was performed. Of the 30 malignant nodules (clinically suspect and solitary nodules) 21 (70%) showed concentrations of 99mTc Bleomycin while only 7 of the 12 solitary malignant nodules did so. Among the 54 benign nodules the false positive rate was 54%. Thermography was positive in 26 (87%) of the 30 malignant nodules and in only 8 (67%) of the 12 solitary malignant nodules. For the 54 benign nodules the false positive rate was 72%. The combined results of the study do not provide any improvement in diagnostic accuracy. Thus it can be said that applications of 99mTc Bleomycin and thermography in the diagnosis of solitary hypofixiant nodules are of limited value.
