Thyroid Imaging Reporting and Data System (TIRADS) in Stratifying Risk of Thyroid Malignancy at The Medical City

Objective: The aim of this study is to determine whether a one-hour image-rich didactic lecture given to sonographers can successfully teach them the TI-RADS (Thyroid Imaging, Reporting and Data System) lexicon, to improve their recognition of malignant thyroid nodules. Methods: A one-hour image-rich didactic lecture on TI-RADS was designed that encompassed the diagnostic criteria for thyroid malignancy and technical tips to better demonstrate thyroid nodules. A lecture was presented to 34 sonographers across multiple sites. The study examined the effects of the lecture by comparing the results of a pretest, an immediate posttest, and a two-week delayed posttest. Results: All 34 sonographers participated in the lecture intervention and each assessment. The prelecture assessment scores ranged from 13% to 73% with an average of 46%. Immediately after the lecture, the assessment scores ranged from 27% to 100%, with an average of 77%. Two weeks after the lectures, scores ranged from 27% to 93%, with an average of 70%. Compared to the pretest, there was a statistically significant increase in average scores immediately after and two weeks after the lecture. Conclusion: It is critically importance to have a reliable, noninvasive method to identify thyroid nodules that have a greater chance of malignancy. A didactic lecture could successfully teach, result in knowledge retention, and increase sonographers’ confidence in the TI-RADS lexicon.

In this study, we aimed to evaluate the diagnostic value of thyroid imaging reporting and data system (TIRADS) in the estimation of malignancy and assess the concordance between TIRADS and the histopathology results of the postoperative specimens. Consecutive ultrasound imaging records of patients with multinodular goiter from January 2010 to December 2017 who underwent surgery were retrospectively reviewed. The risk of malignancy of each TIRADS category was determined, and correlation with pathology was assessed. The patients with malignant cytology findings (Bethesda 6) who were categorized TIRADS 6 were excluded from the study. The positive and negative predictive values, sensitivity, specificity, and accuracy of the TIRADS classification were calculated on a 2 x 2 table with their own formulas. A total of 1457 patients were evaluated, and 1122 of these were included in the study. The risk of malignancy for nodules evaluated as TIRADS 2 was 0.6 per cent, TIRADS 3 was 13.1 per cent, TIRADS 4a was 20 per cent, TIRADS 4b was 61.1 per cent, TIRADS 4c was 85.7 per cent, and TIRADS 5 was 93.3 per cent. The positive predictive value of TIRADS classification was found to be 43.4 per cent, negative predictive value was found to be 90.7 per cent, sensitivity was found to be 78 per cent, specificity was found to be 68.4 per cent, and accuracy was found to be 70.7 per cent for our institution. The TIRADS classification based on suspicious ultrasound findings is reliable in predicting thyroid malignancy and can be routinely used in daily practice.
