[Thermography in the diagnosis of thyroid neoplasms]

Thermographic procedures were used in the examination of 70 patients suspected of bearing thyroid tumors in whom 131I scanning had revealed hypofunction of nodes ("cold" nodes) as well as 38 patients who had been operated for thyroid tumors at different periods. Thermographic diagnosis of primary thyroid tumor was confirmed histologically in 49 cases. Pseudonegative results were established in 5 cases. Pseudopositive results were recorded in 6 out of 21 cases of benign lesions of the thyroid. Recurrences were identified thermographically in 16 patients operated for thyroid tumors. No pseudonegative results were obtained.
