[Comprehensive radiodiagnosis of toxic ademomas of the thyroid]

The results of a comprehensive radionuclide, ultrasound and thermographic study of 18 patients with toxic thyroid adenoma are presented. It has been shown that during thermographic examination temperature difference over the node and the symmetrical region is insignificant and does not exceed 1 degree C in most of the patients. It equally pertains to the comparison of temperatures over the node and the hottest and coldest points in the cervical region. Ultrasound examination makes it possible to determine the shape, size, exact location of the node and its internal structure but gives no opportunity to judge its functional activity. It has been shown that a node in toxic adenoma may have homogeneous as well as heterogeneous echo-structure , elevated or lowered echo-density; changes of degenerative-dystrophic nature are not infrequent.
