Efectividad de la escala EU-TIRADS en la clasificación ultrasonográfica del nódulo tiroideo para realización de PAAF tiroidea versus TI-RADS tradicional

Abstract

Abstract: Ultrasonography evaluation of a thyroid nodule is a necessary method for an adequate approach. The system called EU-TIRADS uses five categories that contain a recommendation according to the risk of malignancy that allows the implementation of other complementary diagnostic resources such as thyroid puncture. In the present study, the effectiveness of EU-TIRADS for the classification of the thyroid nodule was evaluated through the re-reading of thyroid ultrasounds classified with traditional TI-RADS to establish the best indicator for the performance of thyroid FNA in patients in Cytology was performed at the Isidro Ayora General Hospital in the city of Loja in 2018. Cytological and ultrasound reports were collected, and DICOM images were also collected from58 patients, of which 48 were part of the statistical analysis that allowed comparing the effectiveness of the TI-RADS and EU-TIRADS scales, from which sensitivity (72%), specificity (34.78), positive predictive value (0.55), negative predictive value (0.53), OR: 1.056 were obtained., IC: 0.432-2.580. Concluding that the application of EU-TIRADS, would reduce unnecessary punctures.
