Ti-rads classification for diagnosis and classification of thyroid nodules

Abstract

Introduction: The prevalence of thyroid nodule (NT) in the general population is between 2 to 7% by palpation and 19 to 76% by ultrasound. Its incidence is higher with age, in people from iodine-deficient areas, in women, and after exposure to radiation. Objective: To study different bibliographic sources in order to establish the importance of the practical use of the TI-RADS classification in the thyroid nodule. Methodology: It is constituted in a documentary investigation, both bibliographic and digital. Results: The importance of the study of the thyroid nodule lies in the need to exclude cancer, therefore, all thyroid nodule >1cm must be evaluated. Nodules <1 cm will be suspicious when they are associated with risk factors and in the presence of ultrasonographic findings suggestive of malignancy. The TI-RADS classification of TNs based on a scoring system according to the most relevant ultrasound criteria for malignancy has a better and easier application in daily practice. Conclusion: According to the malignancy criteria and the score assigned in this study, the possibility that a NT with one point on the scale is malignant is approximately 10%, while the probability for those with two points is almost 50%. and for those valued with three or four points of 85%. All NTs with 5 or more points are evil. This article summarizes a comparison of bibliographic references for updating and applying the TIRADS classification.
