[Radionuclide study of the thymus gland in myasthenia patients]

Using 75Se methionine the authors performed a scintigraphic examination of the thymus in 65 patients, 15 of whom were suffering from myasthenia and 48 (control) from various neoplastic pathologies of the thyroid and the larynx. The examination has made it possible to discover parts of the thymus active tissue including those remaining after thymectomy. The method enables one to control the results of radiation and surgical treatment of myasthenic patients.
