[The results of an ultrasonic study of the thyroid in patients with nodular goiter who were irradiated as a result of the accident at the Chernobyl Atomic Electric Power Station].
We studied the main values of ultrasonic scanning of patients with thyroid nodes depending on the dose, conditions of irradiation and sex. A total of 281 patients who had received a dose of irradiation of 0.01 to 2.0 Gr were evaluated; of these, 82 took part in the elimination of the effects of the Chernobyl accident (EEA) after evacuation, and 190 subjects were evacuees from the ChNPP 30-km zone, their age ranging between 20 to 68 years. In 43.6% of those having taken part in EEA, thyroid nodes did not exceed 1 cm across, in 44% node diameter was in the range 1 to 2 cm, in 12.4% it exceeded 2 cm. A screening examination revealed volume formations up to 1 cm in 79.5% of the evacuees, 1 to 2 cm across (9.4%), and in 13.02% node diameter exceeded 2 cm. In a major proportion of the examined patients the nodes were hypoechogenous. Distribution of echogenicity of nodes in male subjects does not depend on the dose and period of irradiation. A suggestion is made to the effect that ChNPP accident factors are not involved in the development of nodular forms of goiter in the immediate 7 years following irradiation.
