Introduction: The American College of Radiology proposed in 2017. ACR-TIRADS scoring system for the ultrasound findings of the thyroid gland. It now represents a standardized system of scoring pathological changes determined from five categories registered with ultrasound. High cumulative result leads to higher TR level and the higher probability of malignancy, which provides recommendations for eather FNA (fine needle aspiration) or further ultrasound monitoring of nodules assessed as most likely benign. The aim of the paper is to examine the relationship between ACR TI-RADS scoring system and the cytological findings obtained after the FNA which is represented by the Bethesda system.
Material and methods: Prior to each FNA, TI-RADS was calculated based on the ACR TI-RADS calculator, whereas the type of vascularization of the nodus and the perinodal tissue was determined. The study included 65 patients with the average age of 59 years and average TI-RADS of 3.43. From a total of 65 patients, 72% showed benign cytological finding, whereas 9% were in the AUS or AUS/FLUS category (atypia of undetermined significance/follicular lesion of undetermined significance). The remaining 19% of smears was non-diagnostic. None of the findings obtained had a suspect of malignancy. The average age of patients with benign finding was 58 years, and with AUS was 63 years. It was observed that for patients with AUS the average TI-RADS was 4, and that nodules were positioned in the right lobe, except in one case, where the position was in the area of isthmus. Average TI-RADS in nodules with benign pathohistological findings was 3.3, while 55% were positioned in the left lobe region.Only 6% of patients with benign findings had TI-RADS 1, 15% with TI-RADS 2, TI-RADS 3 had 28% and TI-RADS 4 had 40%, while TI-RADS 5 had 11% of patients. The group of patients with AUS was evenly allocated to results TI-RADS 3, TI-RADS 4, TI-RADS 5 each respresented with 33.3%. Vascularization of nodus type 2 had 34% and 8% had type 4 patient with benign findings,while with AUS findings, 50% of patients had type 2 and 0% type 4. By measuring the volume of nodules, and comparing them, it was found that the average nodus size was greater for patients with the AUS.
Conclusion: There are indications that the higher ACR TI-RADS was obtained in AUS cytological findings. Benign cytological findings were obtained in all TI-RADS 1 and 2.
