NOVEL IN DIAGNOSIS OF NON-CANCEROUS THYROID GROWTHS
Aim. To detect the most sensitive and low-invasive method for diagnosis of con-cancerous growths of thyroid gland. Materials and methods. The results of examination of 735 persons aged 30-50 years with different thyroid growths were analyzed: no pathological growths were revealed in 27 %, adenoma - in 32 %, cyst - in 23 %, malignant neoplasms - in 18 %. For clinical studies, US and transillumination pulsooptometry of the thyroid gland was used. Hemodynamics and optical density were measured by means of Z.M. Sigal device and method. Results. Reliable ( p < 0,05) differences between the cyst and adenoma were found due to investigating pulse oscillation amplitude. Differential diagnosis of large growths on the basis of traditional clinicoroentgenological investigation is difficult. Conventional methods for studying thyroid growths do not give specific signs to differentiate the cyst and adenoma. Conclusions. Combination of pulsography with ultrasonic investigation as a navigational method permits to carry out non-invasive differential diagnosis of non-cancerous growths of the thyroid gland.
