Non-invasive method for determining the level of stable intrathyroid iodine in the diagnosis and control of treatment of thyroid diseases (lecture)

Abstract

The technology of non-invasive determination of the level of intrathyroid stable iodine (ISI), called X-ray fluorescence analysis or X-ray fluorescence scanning, began to be used since 1968 and is currently used in approximately 10 radiological laboratories around the world as a unique research methodology. Only in recent years have the technical difficulties of this diagnostic method been overcome, and it is gradually becoming more accessible. Since 1974, the efforts of the staff of the Radiological Scientific Center of the Russian Academy of Medical Sciences (Obninsk) and the clinical hospital of the Central Health Unit No. 119 of the Federal Administration for Biomedical and Extreme Problems at the Ministry of Health of the Russian Federation (Khimki) carried out the necessary scientific research and created an analyzer, a method for determining the level ISI and interpretations of the results obtained, allowed for use in Russia as serial laboratory technologies. The specified diagnostic method over the past few years has been successfully used in these institutions when examining more than 3,000 patients with various thyroid diseases (thyroid gland) and continues to be used in the comprehensive diagnosis of thyroid pathology. The purpose of this lecture is to familiarize endocrinologists with the diagnostic capabilities of this method.
