Methods and materials

A prospective study in which thyroid ultrasound and FNA biopsy results of 176 patients from Clinical University Hospital and two private clinics were analyzed.

IBM SPSS software, 22.0 version (IBM Corm., Armonk, N.Y., USA), MS Excel 2010 software, and MedCalc Software Ltd 19.2.1 version (Mariakerke, Belgium) was used to analyze statistical data and create graphs. The statistical significance level of this study was assumed to be p-value < 0.05.

Ultrasonographic malignancy signs: markedly hypoechoic, irregular borders, macrocalcifications, taller than wide shape (AP>LL), specific lymphadenopathy.
Ultrasonographic malignancy signs that do not change the TIRADS category: mildly hypoechoic, solid structure, chaotic central type vascularisation, higher stiffness with elastography (if available).
Ultrasonographic malignancy risk-reducing signs: cystic structure, perinodular “halo” sign.
