Abstract
The prevalence of thyroid nodules is high, and the most commonly used imaging modality is ultrasonography (US). Fine needle aspiration biopsy (FNAB) is performed for suspicious nodules after US evaluation, and a guideline called Thyroid Imaging Reporting and Data System (TIRADS) is available to make a biopsy decision. Our study aimed to evaluate TIRADS and Color Doppler Imaging (CDI) findings in nodules together with FNAB results. A total of 83 patients admitted to our hospital between January 2018 and January 2019 were included in this study retrospectively. B-mode US and CDI findings of the nodules, histopathological analysis results were recorded. Diagnostic efficacy of TIRADS classification and CDI findings were evaluated statistically. In our study, 70 (84.34%) of the nodules were found to be benign and 13 (15.66%) were found to be malignant. There was no difference between the benign and malignant groups in the evaluation of blood supply types using CDI (p>0.05). According to B mod US, 6 (27.3%) of 22 lesions with TIRADS 5, 5 (17.9%) of 28 lesions with TIRADS 4 and 2 (6.1%) of 33 lesions with TIRADS 3 were diagnosed as malignant. There was no statistically significant relationship between TIRADS categories and blood supply types in malignant lesions (p> 0.05). CDI examination of thyroid nodules did not reveal any blood supply patterns that could be significant for malignancy. CDI findings are not guiding to decide for FNAB.

Key words: Doppler, thyroid nodule, TIRADS, ultrasonography
