Objective:a comparative “blind” assessment of the thyroid nodules identified by ultrasound, according to the TI-RADS scale in various modifications.Materials and methods.Retrospective analysis of 149 echograms of thyroid nodules by three independent experts was performed (the experience of ultrasound of thyroid ultrasound for more than 7 years).Results. In solid nodules, high-specific large (more than 94%) and small (more than 90%) ultrasound signs of thyroid cancer have been identified. The nodes are stratified according to the TI-RADS system: 1 – in the modification J.Y. Kwak et al. (2011), 2 – according to the proposed system, taking into account small ultrasound signs of thyroid cancer. High reproducibility of both systems are obtained. In the first system 13.7% of cancer nodes fell into the category of TI- RADS 3 (benign formations), in the second system only 5% of cancers fell into the category of TI-RADS 3, which is important for biopsy selection. The sensitivity of the first system was TI-RADS 82.05%, of the second system – 94.87%.Conclusions.Classification of TI-RADS can be used to interpret the ultrasound results of thyroid nodules, taking into account both the main large and small ultrasound signs of cancer. For its validation in our country, it is necessary to further broad discussion of the proposed TI-RADS system.
